Question

What is the product of following reaction?
HI / Red P
?
CH3COOH​

Answer 1

Step-by-step explanation:

CH

3

COOH+Cl

2

RedP

−HCl

A

ClCH

2

COOH

Acetic acid reacts with chlorine in presence of red phosphorous to form monochloro acetic acid. Alpha H atom is replaced with Cl atom. Hence, the compound is ClCH

2

COOH.

HVZ reaction is haogenation of carboxylic acids at alpha carbon atom. In this reaction red-P and chlorine is treated with carboxylic acids having alpha hydrogen atom followed by hydrolysis to form alpha chloro carboxylic acid.
