Identiy Z in the reaction.

A

dichloromethyl cation `(underset(+)(C)HCl_(2))`

B

formyl cation `(underset(+)(C)HO)`

C

dichloromethyl anion `(underset(-)(C)HCl_(2))`

D

dichorocarbene `( : C Cl_(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
It is an example of Reimer Tiemann reaction. The electrophile involved in the reaction is dichlorocarbene `( : C Cl_(2))` and is formed as follows :
`{:(CHCl_(3),+,OH^(-),hArr,overset(..)(C)Cl_(3)+H_(2)O),(,,,,darr-Cl^(-)),(,,,,:C Cl_(2)),(,,,,"Dichlorocarbene (electrophile)"):}`
