The reaction given below is an example of Friedel-Craft alkylation reaction.

In number of cases of Friedel-Crafts alkylation, the final product is found to contain a rearranged alkyl group. Generally with stronger Lewis acid product is rearranged due to enough polarization of complex while with weak lewis acid no such effect is observed. Temperature also favours rearranged product.
If we take `FeCl_(3)` in place of `AICI_(3)` in the above reaction, the product is

A

only (A)

B

Only (B)

C

(A) and (B) both can be possible

D

Not given

Text Solution

Verified by Experts

The correct Answer is:
A
Lewis acid generates the electrophile. `FeCl_(3)` also acts as a Lewis acid. Thus, replacement of `FeCl_(3)` in place of `AICI_(3)` would not affect the product.
