Question

Identify the carboxylic acid chloride that might be used in a Friedel-Crafts reaction to prepare the following acyl benzene.

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is C

Friedel-Crafts Acylation : One H atom attached to C atom of the ring gets replaced by Acyl $\left(RCO\right)$ group.

The attacking electrophile is an acyl carbocation $\left(R\stackrel{+}{C}O\right)$ made available by Acid halide $\left(RCOX\right)$.


Hence, the correct answer is option (c).
