Question

Phenol can be converted into salicyladehyde 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

Perkin's 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 $\alpha$-hydrogen atom. It is a disproportionation reaction.
$2HCHO\stackrel{50\%NaOH}{\to }HCOONa+C{H}_{3}OH$
