Question

Which one of the following will be reactive for Perkin condensation ?

• A. $C_6H_5 - CHO$
• B.
• C.
• D.

Answer 1

Answer: (D)

Answer 2

(i) This reaction occurs between an aromatic aldehyde and an aliphatic anhydride having at least two $\alpha- H$ atoms.

(ii) Electron attracting groups attached to the ring increases the efficiency of Perkin condensation while electron releasing groups (electron donating group) decreases the efficiency of Perkin's reaction.

Hence

be the most reactive towards perkin's condensation.
