Vedclass · Answer

(B) In the Friedel-Crafts alkylation of benzene with $n$-propyl chloride $(CH_3CH_2CH_2Cl)$ in the presence of anhydrous $AlCl_3$,the primary carbocation $(CH_3CH_2CH_2^+)$ is initially formed.This primary carbocation is unstable and undergoes a $1,2$-hydride shift to form a more stable secondary carbocation,which is the isopropyl carbocation $(CH_3-\stackrel{\oplus}{C}H-CH_3)$.

The stable carbocation formed in the reaction of benzene with $n$-propyl chloride in the presence of anhydrous $AlCl_3$ is:
