Wurtz-Fittig reaction

Vedclass · Answer

(C) $n$-propyl benzene is best prepared using the Wurtz-Fittig reaction.
In this reaction,an alkyl halide $(CH_3CH_2CH_2Br)$ reacts with an aryl halide $(C_6H_5Br)$ in the presence of sodium metal and dry ether.
The reaction is: $CH_3CH_2CH_2Br + C_6H_5Br + 2Na \xrightarrow{	ext{dry ether}} C_6H_5CH_2CH_2CH_3 + 2NaBr$.
Friedel-Craft's alkylation is unsuitable because the $n$-propyl carbocation intermediate undergoes rearrangement to a more stable isopropyl carbocation,leading to isopropyl benzene as the major product.

Which one of the following reactions is most suitable for the preparation of $n$-propyl benzene?
