Why should the monomers used in addition to polymerization through free radical pathway be very pure?
This is a short answer type question as classified in NCERT Exemplar
Monomers used in addition to polymerization through free radical pathway should be very pure because even the traces of impurities acts like inhibitors. It leads to the formation of polymers with a shorter chain lengths.

Which type of biomolecules have some structural similarity with synthetic polyamides? What is this similarity?
This is a short answer type question as classified in NCERT Exemplar
Proteins have some similar structural similarities with synthetic polyamides. Proteins and polyamides both contain amide linkage.

Name the polymers used in laminated sheets and give the name of monomeric units involved in its formation.
This is a short answer type question as classified in NCERT Exemplar
Urea-formaldehyde resin is used in laminated sheets. The monomer involved in the formation of urea formaldehyde resin is urea and formaldehyde.
Upvote Which factor imparts crystalline nature to a polymer like nylon?
Which factor imparts crystalline nature to a polymer like nylon?
This is a short answer type question as classified in NCERT Exemplar
Polymers that possess amide linkage are termed as nylon. Fibers have a strong intermolecular force of attraction like hydrogen bonding. It leads to the close packing of the structure which imparts the crystalline nature.

What is the role of benzoyl peroxide in addition polymerisation of alkenes? Explain its mode of action with the help of an example.
This is a short answer type question as classified in NCERT Exemplar
Free radicals are generated from benzoyl peroxide. Alkanes, dienes are polymerized in the presence of free radical inhibitors like benzoyl peroxide, acetyl peroxide. For example, benzoyl peroxide inhibitor is used for the polymeriza
Upvote What is the structural difference between HDP and LDP? How does the structure account for different behaviour and nature, hence the use of a polymer?
What is the structural difference between HDP and LDP? How does the structure account for different behaviour and nature, hence the use of a polymer?
This is a short answer type question as classified in NCERT Exemplar
LDP: The polymerization of ethene under high pressure and temperature in the presence of peroxide catalyst gives low-density polythene. It is obtained through free radical addition and has a high branched structure. It is chemically
