b) 2-chloro-1,3-butadiene

c) 1-methyl-1,3-butadiene

d) 2-methyl-1,3-butadiene

Solutions

Expert Solution

Answer : b) 2-chloro-1,3-butadiene 

Explanation :

Neoprene or polyisoprene is a synthetic rubber obtained from the addition polymerisation of chloroprene

2-chloro-1,3-butadiene  ----> Neoprene 

through free radical mechanism. It has a better stability towards oxidation than natural rubber. Neoprene is good synthetic rubber as well as good alternative for natural rubber.

b) 2-chloro-1,3-butadiene
