Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Alkyl benzene is not prepared by Friedel-Craft's alkylation of benzene.
Di, tri alkylated benzenes are also formed in addition to monoalkylated benzene and the separation of these products is difficult.
Alkyl benzene is prepared by Friedel-Craft's alkylation of benzene followed by reduction of acyl benzene to alkyl benzene. This gives mno alkylated product.
Alkyl halides are less reactive than acyl halides.
The carbonyl C atom is more electrophilic than C atom of alkyl haliodes.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
