Question

During addition polymerization of ethane molecules, the initiator like benzoyl peroxide, acetyl peroxide, tert-butyl peroxide, etc. are added. Their function is to:

• A. ensure anti-Markownikoffs addition of molecules to form polymer
• B. give cations during the reaction which join together to form bigger molecules
• C. decrease the temperature of the reaction mixture
• D. generate free radical which adds to the monomer to give bigger free radical

Answer 1

The correct option is D generate free radical which adds to the monomer to give bigger free radical

An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products

Example- Polyethene, Teflon, Polystyrene, Orlon etc.

Free radical addition takes place in the presence of free radical generating initiator like benzoyl peroxide, acetyl peroxide, tert-butyl peroxide, the work of free radical initiator is given in the image.

The correct option is [D].
