A) Perkin's reaction
B) Cannizzaro's reaction
C) Sandmeyer's reaction
D) Claisen condensation
Correct Answer: B
Solution :
Benzaldehyde on treatment with 50% aqueous or ethanolic alkali solution undergoes Cannizzaro?s reaction like \[HCHO\] (no \[\alpha \]-hydrogen atom) i.e., one molecule is oxidised and one is reduced with the formation of benzoic acid and benzyl alcohol respectively. \[2{{C}_{6}}{{H}_{5}}CHO\xrightarrow{NaOH}{{C}_{6}}{{H}_{5}}C{{H}_{2}}OH+{{C}_{6}}{{H}_{5}}COONa\]
