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
