Q. $\Phi CHO$ undergoes Claisen condensation with another aldehyde to give cinnamaldehyde. The aldehyde is
A) Formaldehyde
B) Acetaldehyde
C) Crotonaldehyde
D) Propanaldehyde
Explanation
(b)
Cinnamaldehyde is prepared by the Claisen reaction between benzaldehyde and acetaldehyde
$C_{6}H_{5}CHO + CH_{3}CHO\overset{\ \ NaOH\ \ }{\rightarrow}\ C_{6}H_{5}OH = CHCHO + H_{2}O$
cinnamaldehyde
