NEET levelSingle correct optionDifficulty 1 of 3pl050

Orlon (polyacrylonitrile) is obtained by addition polymerisation of

A $CH X_{2} = CH - CN$
B $CH X_{2} = CH - Cl$
C $CH X_{2} = CH - COOCH X_{3}$
D $CH X_{2} = C (CH X_{3}) - COOCH X_{3}$

Answer: A

Acrylonitrile,

CH X_{2} = CH - CN

, is the monomer of polyacrylonitrile (Orlon). The others give PVC, poly(methyl acrylate) and PMMA.
