Chemistry Question on Polymers

The monomer used to produce orlon is

A

CH2=CHFCH_{2} =CHF

B

CH2=CCl2CH_{2} =C Cl_{2}

C

CH2=CHClCH_{2} =C H Cl

D

CH2=CH−CNCH_{2} =CH -CN

Answer

CH2=CH−CNCH_{2} =CH -CN

Explanation

Solution

Orion is poly vinyl cyanide which is a polymer of vinyl cyanide (or acrylonitrile).
nCH2=CH−CNvinyl cyanide→−[−CH2−CC∣NH−]n−orlon\underset{\text{vinyl cyanide}}{nCH_2 = CH - CN} \to \underset{\text{orlon}}{-\left[-CH_2-\underset{\overset{|}{C}N}{C}H-\right]_n-}
