What are the similarities between addition polymerization and condensation polymerization?
Polymerization describes the formation of of large molecules (polymers) with repeating structure from smaller molecules (monomers) . The word polymer comes from Greek words meaning many (poly-) and parts (-mer). Many of the resulting molecules are plastics, so polymer is occasionally used in place of the word plastic, though this is not an accurate usage. Polymerization is an all-encompassing term that describes formation of polymers by any method.
There are two main types of polymerization; addition polymerization and condensation polymerization. Addition polymerization creates larger molecules by opening up double bonds on the smaller molecules (monomers). These opened-up bonds react with parts of other monomers (single part) to form dimers (double part). This reaction can repeat to add another molecule to for a trimer (three part). This continues until you obtain the right size molecule and you stop the reaction. Addition polymerixation can occur using a single type of monomer. There are no by products of the reaction except the longer chain molecules (polymers).
In condensation polymerization, two monomers of different types are used. They have different types of reactive (or functional) groups on them. A reaction between monomer A and monomer B results in a dimer, plus another small molecule (often water) that is not part of the polymer. To create long polymers the monomers must have reactive groups on both ends or a chain cannot be formed.
Polymerization is an all-encompassing term for creating polymers by any method. Condensation Polymerization is a term denoting a specific type of reaction for creating polymers.
What else can I help you with?
Polymerization and the breakdown of a polymer are two opposite reactions What role does a water molecule play in both of them?
In polymerization, a water molecule is often eliminated as a byproduct in a condensation reaction between monomers. This process is known as dehydration synthesis. In the breakdown of a polymer via hydrolysis, water molecules are used to break the covalent bonds between monomers, resulting in the degradation of the polymer into its constituent monomer units.
What is adition polymerisation?
it is the fusing together of monomers and hydrocarbons by using heat.addition to above answere.it is the addition of monomer molecules to form bigger particle which is called polymer.the reaction is carried out by heat, and catalyst like potassium per sulphate,cumene peroxide,s.m.b.s.etc.as well as emusifier is must for emulsion polymerisation.the molecular wt. of polymer is much more than monomer.
How does 4 nucleotides polymerize to form nuclic acid?
Nucleotides polymerize through a condensation reaction between the phosphate group of one nucleotide and the sugar group of another nucleotide. This forms a phosphodiester bond, linking the nucleotides together to form a nucleic acid chain. DNA and RNA are examples of nucleic acids formed by polymerization of nucleotides.
What is the type of reaction that occurs when complex molecules are formed from simpler molecules and water is removed?
The condensation polymerization takes place by removal of water molecules from organic molecules as formation of Bakelite , Terylene and Nylon. in plants starch is also formed by this mechanism from Glucose molecules.
What the differences between ring-opening polymerization and ring-opening metathesis polymerization?
Ring-opening polymerization involves the opening of cyclic monomers with formation of linear polymer chains, while ring-opening metathesis polymerization involves the redistribution of double bonds in cyclic monomers to form a polymer chain. Ring-opening polymerization can use a variety of monomers, whereas ring-opening metathesis polymerization is typically limited to cyclic olefins. Additionally, ring-opening polymerization relies on nucleophilic or electrophilic initiators, while ring-opening metathesis polymerization relies on metal catalysts.
Why is condensation polymerization known as step growth polymerization?
condensation polymerization takesplace in a step wise manner.In addition polymerization monomers react to form polymers and there is no biproduct formation.In condesation polymerisation, byproducts are formed in every steps called as dimer,trimer.tetramer etc...
What are the differences between additional polymerization and condensation polymerization?
the structural unit of step reaction polymerization are chemically identical to the monomer employed in the reaction while those of the chain reaction may or may not be identical addition or step polymers take their names from their starting monomers while those of the chain reaction is not so
What is the chemical reaction by which monomers are linked together to form polymers?
The chemical reaction that links monomers together to form polymers is called polymerization. During polymerization, monomers undergo a process where their chemical bonds are broken and new bonds are formed between the monomer units, resulting in a chain-like structure of repeating units known as a polymer. This process can be initiated by heat, light, or the addition of a catalyst.
What chemical reaction formed these large molecules?
Large organic molecules (macromolecules) are generally formed by condensation reactions between smaller molecules.Condensation means that a small molecule is formed from the atoms removed during the reaction. In cells, the small molecule is water, so the type of condensation reaction is dehydration.Examples:glucose + (chain of n glucose residues) forms chain of n + 1 residues + wateramino acid + (chain of n amino acid residues) forms chain of n + 1 residues + water
Watt are the Similarities and difference between suspension and emulsion free polymerization?
Similarities: Both suspension and emulsion free polymerization techniques involve dispersing monomer droplets in water to form polymer particles. Differences: In suspension polymerization, monomer droplets are dispersed directly in the aqueous phase, while in emulsion polymerization, an emulsifier is used to stabilize the monomer droplets and prevent coalescence. Emulsion polymerization typically results in smaller particle sizes and a more stable polymer dispersion compared to suspension polymerization. Emulsion polymerization allows for the incorporation of water-insoluble monomers and surfactants, while suspension polymerization is limited to water-soluble or water-dispersible monomers.
How does condensation polymerization takes place?
Condensation polymerization occurs when monomers with two or more functional groups, such as -OH or -COOH, react to form a polymer chain along with the release of a small molecule like water or HCl. This reaction involves the formation of covalent bonds between monomers through condensation reactions, leading to the growth of the polymer chain. The process continues until all the monomers have reacted or the polymer reaches a desired length.
What is the condensation polymerization reaction between 2 amino acids to form a peptide bond?
Condensation polymerization between two amino acids involves the removal of a water molecule to form a peptide bond. One amino acid donates an amine group (-NH2) while the other donates a carboxyl group (-COOH), forming a peptide bond (-CO-NH-). This reaction occurs through a nucleophilic acyl substitution reaction.
What is the process in which alkene monomers join to form chains?
Alkene monomers join together through a process called polymerization, specifically in a reaction known as addition polymerization. This involves the breaking of the double bond in the alkene monomers and the formation of new single bonds between the carbon atoms, thus creating a chain-like structure known as a polymer. This reaction is typically catalyzed by a catalyst such as a transition metal complex.
Similarities between dehydration synthesis and hydrolysis?
Condensation reaction creates a covalent bond between 2 interacting subunits, linking them to each other while hydrolysis reaction is a catabolic reaction in which a water molecule is used to break a covalent bond holding subunits together.
Define the type of chemical reaction involved in the formation of a peptide linkage between two amino acids and state the other product in addition to a dipetide?
The formation of a peptide linkage between amino acids is a condensation reaction, specifically a dehydration synthesis reaction. The other product in addition to the dipeptide is a molecule of water.

What are the similarities and differences between evaporation and condensation?
Evaporation and condensation both involve the phase change of a substance from liquid to gas or gas to liquid. The main difference is that evaporation is the process where a liquid turns into a gas due to heat energy, while condensation is the process where a gas turns into a liquid due to cooling. Evaporation usually occurs at the surface, while condensation can occur anywhere in the gas phase.
