In the reaction the electrophile involved is:

A

Dichloromethyl cation `(overset(oplus)CHCl_(2))`

B

Formyl cation `(overset(oplus)CHO)`

C

Dichlorocarbene `( :"C Cl_(2))`

D

Dichloromethyl anion `(overset(oplus)CHCl_(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
It is Reimer-Tiemann reaction the electrophile formed is `:C Cl_(2)` (Dichlorocarbene) according to the following reaction
`CHCl_(3)+OH^(-)iffoverset(..)(C)Cl_(3)+H_(2)O`
`overset(..)(C)Cl_(3)rarrunderset("Electrophile")( :C Cl_(2))+Cl^(-)`
