Write the names and structures of the monomers of the following polymers:
(i)Buna-S,(ii)Buna-N
(iii)Dacron,(iv)Neoprene

Explanation

The names and structures of the monomers are :
(i) Buna-S : `CH_(2)=underset(1,3-"Butadiene")(CH-CH=CH_(2)) and underset("Stryene")(C_(6)H_(5)-CH=CH_(2))`
(ii) Buna -N : `CH_(2)=underset(1,3-"Butadiene")(CH-CH_(2)) and CH_(2)=underset("Acrylonitrile")(CH-CN)`
(iii) Neoprene : `underset("Chloroprene or 2-chloro-1,3-butadiene")(CH_(2)=overset(CI)overset(|)(C)-CH=CH_(2)`)
(iv) Dacron :`underset("Ethylene glycol")(HO-CH_(2)-OH and)`
