Q85 / 180 · NEET 2018 · Chemistry

In the reaction, the electrophile involved is

A
Dichloromethyl anion $(\overset{⊝}{C} {HCl}_{2})$
B
Formyl cation $(\overset{\oplus}{C} HO)$
C
Dichloromethyl cation $(\overset{\oplus}{C} {HCl}_{2})$
Correct answer
D
Dichlorocarbene $(: {CCl}_{2})$

Solution

The Reimer Tiemann reaction is an organic chemical reaction where phenol is converted into an ortho hydroxy benzaldehyde using chloroform, a base, and acid workup. This results in a nucleophilic attack on the dichlorocarbene, forming an intermediate dichloromethyl substituted phenol.

Hence, the correct answer is option: 'D'.
