Examine the structural formula of the following compounds. `C_(2)H_(4)`, `CH_(3)Cl`, `C_(2)H_(2)Cl_(2)`, `C_(2)H_(2)`,`C_(3)H_(8)`,`C_(3)H_(6)`,`C_(3)H_(4)`,`C_(3)H_(3)Cl` classify them as in the following manner.
a) Molecules which undergo substitution reaction
b) Molecules which undergo addition reaction.
c) Molecules which can ploymerise.

Explanation

a) The Compounds undergo substitution reaction `CH_(3)Cl, C_(3)H_(8)`
b) The compounds undergo both substitution and polynerisation reaction: `C_(2)H_(4), C_(2)H_(2)Cl, C_(2)H_(2), C_(3)H_(6), C_(3)H_(4), C_(2)H_(3)Cl`
