Why are unsaturated monomers used in addition polymerisation?
Unsaturated monomers are used in addition polymerization because they contain carbon-carbon double bonds that can readily undergo addition reactions to form long polymer chains. This allows for the efficient production of high molecular weight polymers without the formation of byproducts. Additionally, unsaturated monomers grant flexibility to control the properties of the resulting polymer by modifying the monomer structure.
What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
Why benzene did not give straight chain structure?
straight chain structure for C6H6 may be CH2=CH-C=C-CH=CH2 (two double and one triple bond) . but if it is so then it should undergo the addition reactions easily.but in actual practice benzene does not undregoes addition reaction easily and not reacts with HCl , Br2 and KMnO4 solutions......
Do aromatic compounds undergo additon reactions?
Aromatic compounds typically do not undergo addition reactions. Their stability is due to the delocalized pi-electrons in the aromatic ring, making them less reactive towards addition reactions. Instead, aromatic compounds often undergo substitution reactions.
How formaldehyde undergo addition reaction?
Formaldehye is H2C=O and has a double bond. The Carbon-oxygen bond is slightly polar and the carbon has partial positive charge and oxygen slightly negative charge. Hence formaldehyde will undergo nucleophilic addition addition reaction across the C=O.

Describe the formation of polyethene as an example of additional polymerisation of monomer units?
Alkene such as ethene contain c=c double bond.Hence these molecules can take part in addition reaction where the double bond is broken and other atoms attach to the carbon across the double bond to form large molecule such as polyethene. Here the ethene is the monomer and polyethene the addition polymer which is formed under high pressure, heat and by using a catalyst.
Does propane undergo addition reaction?
Propane does not typically undergo addition reactions due to its stable structure as a saturated hydrocarbon. It is not reactive under normal conditions and tends to undergo combustion or substitution reactions rather than addition reactions.

Is a steroid a monomer or polymer?
A steroid is a type of organic compound that is not classified as a monomer or polymer. Steroids are made up of a specific chemical structure consisting of four interconnected rings, and they do not undergo polymerization like monomers do to form polymers.
Would C6H12 react by addition or substitution reactions?
C6H12 is a general formula for cycloalkanes, which typically undergo substitution reactions due to the presence of stable sigma bonds within the ring structure. Addition reactions are more characteristic of unsaturated hydrocarbons like alkenes and alkynes.
Do aromatic compounds undergo additon reactions?
Aromatic compounds typically do not undergo addition reactions. Their stability is due to the delocalized pi-electrons in the aromatic ring, making them less reactive towards addition reactions. Instead, aromatic compounds often undergo substitution reactions.
What is the relationship between the CO2 resonance hybrid structure and its impact on the molecule's properties?
The CO2 molecule has a resonance hybrid structure, which means that it exists as a combination of two different Lewis structures. This resonance hybrid structure affects the molecule's properties by making it linear in shape, nonpolar, and unable to undergo reactions like addition or substitution.
How formaldehyde undergo addition reaction?
Formaldehye is H2C=O and has a double bond. The Carbon-oxygen bond is slightly polar and the carbon has partial positive charge and oxygen slightly negative charge. Hence formaldehyde will undergo nucleophilic addition addition reaction across the C=O.
When alkenes undergo addition reaction what kind of bond does it produce?
When alkenes undergo addition reactions, they typically form a new single bond, resulting in a saturated compound. This is because the double bond in the alkene is broken, allowing the addition of atoms or groups to each carbon of the original double bond.
