Question

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

Answer 1

Answer:

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.

Answer 2

• We are required to find the product formed when acetic acid reacts with Red phosphorus and HI.
• Here the 'reactant' is Acetic Acid and HI
• When Acetic acid (CH₃COOH) reacts with Red Phosphorus and HI, it gets reduced to Ethane (CH₃-CH₃).

               CH₃COOH + 6 HI ----------> CH₃ - CH₃ + 2H₂O + 3I₂

• It is a reduction reaction where carboxylic acid reduces into alkane.
