    Assertion (A) Friedel-Crafts reaction of benzene with n-propyi chloride on heating produce isopropyi benzene. Reason (R) Benzene undergoes electrophilic substitution easily. Each of these questions contains two statements. Assertion (A) and Reason (R). Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

    C) If Assertion is true but Reason is false.

    D) If both Assertion and Reason are false.

    Correct Answer: B

    Solution :

    The initially formed n-propyi cation first undergoes rearrangement by 1, 2-hydride shift to form the more stable isopropyi cation which then attacks the benzene ring to form isopropylbenzene.
