Phenol can be converted into salicylaldehyde by

A)  Etard reaction

B)  Perkin reaction

C)  Cannizaro reaction

D)  Reimer-Tiemann reaction

Correct Answer: D

Solution :

                Phenol can be converted into salicylaldehyde by Riemer-Tiemann reaction. Etard reaction-Converts toluene into benzaldehyde Perkins reaction Benzaldehyde + acid anhydride \[\xrightarrow[acid]{Salt\,of}\] \[\alpha ,\beta \]-unsaturated acid Cannizaro reaction-This reaction is shown by aldehydes which do not have a-hydrogen atom. It is a disproportionation reaction. \[2HCHO\xrightarrow{50%\,\,NaOH}HCOONa+C{{H}_{3}}OH\]
