Question

Identify the products (X) and (Y)in the given reaction.

• A. X=Acetophenone, Y=m-Nitroacetophenone
• B. X=Toluene, Y=m-Nitroacetophenone
• C. X=Acetophenone, Y=o-and p-Dinitroacetophenone
• D. X=Benzaldehyde, Y=m-Nitroacetophenone

Answer 1

The correct option is A X=Acetophenone, Y=m-Nitroacetophenone

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

The attacking electrophile is an acyl carbocation $RCO\stackrel{+}{)}$ made available by Acid anhydride $\left(\right(RCO{)}_{2}O)$.
$-COC{H}_3$ is one of the strongest deactivating group, it reduces the electron density at ortho and para position by -R effect. Hence, it is a meta-directing group.
Hence, the correct answer is option (a).
