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

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 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.
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 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.
Can liquid soap wiped on windows stop condensation?
Liquid soap will not prevent condensation on windows. Condensation is caused by differences in temperature and humidity between the inside and outside of a window. To prevent condensation, you can try using a dehumidifier, improving ventilation, or installing insulated windows.
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.
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
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.
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.
Large organic molecules are usually assembled by polymerization of a few kinds of repeating simple subunits what is an exception to this statement?
An exception to this statement is the assembly of lipid molecules, such as fats and oils, which are not formed by polymerization of repeating subunits but rather by condensation reactions between individual fatty acid molecules and glycerol molecules. Lipids do not form polymers in the same way that proteins, nucleic acids, and carbohydrates do.
