Which among the following is NOT an example of Wurtz reaction?
  1. $2 \mathrm{C}_2 \mathrm{H}_5 \mathrm{Br}+2 \mathrm{Na} \stackrel{\text { dry ether }}{\longrightarrow} \mathrm{C}_4 \mathrm{H}_{10}+2 \mathrm{NaBr}$
  2. $\mathrm{CH}_3 \mathrm{Br}+\mathrm{C}_2 \mathrm{H}_5 \mathrm{Br} \underset{\text { dry ether }}{\stackrel{\mathrm{Na}}{\longrightarrow}} \mathrm{C}_2 \mathrm{H}_6+\mathrm{C}_3 \mathrm{H}_8+\mathrm{C}_4 \mathrm{H}_{10}$
  3. $2 \mathrm{CH}_3 \mathrm{Br}+2 \mathrm{Na} \stackrel{\text { dry ether }}{\longrightarrow} \mathrm{C}_2 \mathrm{H}_6+2 \mathrm{NaBr}$

Solution

Fittig reaction Rest 3-reaction are Wurtz reaction.
