C

Dichloromethyl anion `(overset(Theta)CHCl_2)`

D

Dichlorocarbene `( : C Cl_2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Reimer - Tiemann reaction

Mechanism:
(i) Generation of electrophile
`CHCl_3+NaOH" " tounderset(("electrophile"))underset("Dichlorocarbene")( :C Cl_2)+H_2O+NaCl`
