Phenol can be converted into salicylaldehyde by

• A. Etard reaction
• B. Perkin reaction
• C. Cannizaro reaction
• D. Reimer-Tiemann reaction

Answer 1

Answer: (D)

Phenol can be converted into salicylaldehyde by Riemer-Tiemann reaction.
Etard reaction-Converts toluene into benzaldehyde
Perkins reaction Benzaldehyde $+$ acid anhydride $\underset{\text{acid}}{\overset{\text{ Salt of }}{\to }}\alpha ,\beta$-unsaturated acid Cannizaro reaction-This reaction is shown by aldehydes which do not have a-hydrogen atom. It is a disproportionation reaction.
