Assertion : Alkyl benzene is not prepared by Friedel Craft alkylation of benzene.
Reason : Grignard reagents react with hydroxyle group

Options

A. If the both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true and the reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false statements.

Answer

B

Explanation

The monoalkyl derivative first formed readily undergoes further alkylation at a still greater speed to produce polysubstitude products, and alkyl halide employed may also undergo an isomeric change. Due to these difficulties alkyl benzene is not generally prepared by Friedel-Craft's alkylation of benzene.
