Question

Which one of the following monomers gives the polymer neoprene on polymerization?


A
CF2=CF2
loader
B
CH2CHCl
loader
C
CCl2=CCl2
loader
D
CH2=Cl|CCH=CH2
loader

Solution

The correct option is C $$CH_2 = \overset{Cl}{\overset{|}{C}}-CH = CH_2$$
Neoprene is produced by polymerization of chloroprene.
Chloroprene is the common name for 2-chlorobuta-1,3-diene with the chemical formula $$CH_2=CCl−CH=CH_2$$.
Hence, option $$D$$ is correct.
