Which amongst the following molecules on polymerization produces neoprene?

A

(1) H2C=CHCH=CH2H_2C = CH - CH = CH_2

B

(2) H2C=C(Cl)CH=CH2H_2C = C(Cl) - CH = CH_2

C

(3) H2C=CHCCHH_2C = CH - C \equiv CH

D

(4) H2C=C(CH3)CH=CH2H_2C = C(CH_3) - CH = CH_2

Step-by-Step Solution

Neoprene is a polymer of chloroprene, which is 2-chloro-1,3-butadiene. The structure is H2C=C(Cl)CH=CH2H_2C = C(Cl) - CH = CH_2.
