The functional group which is formed when Phenol is made to react with Chloroform in the presence of dilute Sodium hydroxide

Question

The functional group which is formed when Phenol is made to react with Chloroform in the presence of dilute Sodium hydroxide (A) -CH2Cl (B) -COOH (C) -CHCl2 (D) -CHO

Tardigrade Admin · Accepted Answer

The reaction of phenol with chloroform in presence of dilute sodium hydroxide finally introduces aldehyde -CHO functional group and hydroxy group at -ortho position. The reaction is known as the Reimer Tiemann reaction. Reimer Tiemann reaction: <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-pfjwmlxjbvtuwlkh.jpg" />
