Q.
Which method is preferred for the preparation of $n$-propyl chloride from benzene?
Hydrocarbons
Solution:
Wurtz-Fittig method is preferred since in this case, no rearranged product is formed. As far as other products, viz. $n$-hexane and biphenyl is concerned, these can be easily removed from n-propyl benzene by distillation since their boiling points differ very much from each other.
