Choose the Wrong statement amongst the following

Moderate

A

Chlorine water on long standing loses its yellow colour due to the formation of HCl and HOCl
B

The composition of bleaching power is Ca(OCl)₂.CaCl₂.Ca(OH)₂.2H₂O
C

The bleaching action of chlorine water is due to reduction
D

Chlorine gives addition products with low molecular weight unsaturated hydrocarbons.

Solution

The bleaching action of chlorine water is due to oxidation.
H₂O + Cl₂→ HCl + HOCl.
Hypochlorous acid is unstable and decomposes to give nascent oxygen.
Thus moist chlorine acts as oxidant and bleaching agent.
HOCl →HCl + (O)
