Which of the following types of reaction occur when a reactant has got a double bond ?
(i) Addition
(ii) Photolysis
(iii) Nucleophilic substitution
(iv) Polymerization
  1. (i) and (iv)
  2. (i) and (ii)
  3. (i), (ii) and (iv)
  4. (i), (ii), (iii) and (iv)

Solution

Addition reaction occurs on a double bond. The compound containing double bonds are also undergo polymerisation. So, the correct option are both (i) and (iv) e.g.
$\mathrm{CH}_{2}=\mathrm{CH}_{2}+\mathrm{HOCl} \longrightarrow \mathrm{CH}_{2} \mathrm{OH}-\mathrm{CH}_{2} \mathrm{Cl}$
(addition reaction)
$n \mathrm{CH}_{2}=\mathrm{CH}_{2} \stackrel{\text { Polymerisation }}{\longrightarrow}\left[\mathrm{CH}_{2}-\mathrm{CH}_{2}ight]_{\mathrm{n}}$ .
