Vedclass · Answer

(B) The reaction described is the $Perkin$ reaction. In this reaction,an aromatic aldehyde (e.g.,$Benzaldehyde$) reacts with an acid anhydride (e.g.,$Acetic$ $anhydride$) in the presence of the sodium salt of the corresponding acid (e.g.,$CH_3COONa$) to yield an $\alpha,\beta$-unsaturated aromatic acid (e.g.,$Cinnamic$ $acid$ after hydrolysis). The general reaction is: $ArCHO + (RCH_2CO)_2O \xrightarrow{RCH_2COONa} ArCH=C(R)COOH + RCH_2COOH$.

In which of the following reactions does an aromatic aldehyde react with an acid anhydride in the presence of the salt of the corresponding acid to form an unsaturated aromatic acid?
