Question

The reaction(s) that give(s) tert-butylbenzene as the major product is/are

• A. A
• B. B
• C. C
• D. D

Hint:

Friedel–Crafts alkylation depends on stability of carbocationTertiary carbocations give tert-alkylbenzene as product

Answer 1

The Correct Option is A, C

Step 1: What makes the product.
tert-Butylbenzene forms by Friedel-Crafts alkylation, so any route that gives a tert-butyl cation works.

Step 2: Check the routes.
tert-Butyl chloride with aluminium chloride gives the tert-butyl cation, and isobutylene with acid also gives it. Both lead to the product.

Step 3: Reject the others.
Isopropyl chloride gives cumene, and the Grignard route does not do Friedel-Crafts alkylation.

Step 4: Answer.
\[ \boxed{\text{A and C}} \]
