Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Benzene reacts with n-propyl chloride in presence of AlCl3/Δ to give isopropyl benzene because benzene undergoes electrophilic substitution readily. CH3−CH2−CH+2→CH3−CH+−CH3
The primary carbocation (n-propyl cation) rearranges to more stable secondary carbocation (isopropyl cation) to give the rearranged product.
Hence, both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
