Which is the best description of the behaviour of bromine in the reaction given below
`H_(2)O+Br_(2) rarr HOBr+HBr`

A

Proton acceptor only

B

Both oxidized abd reduced

C

Oxidized only

D

Reduced only

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)O+ overset(0)(B)r_(2) rarr HO overset(+1)(B)r+Hoverset(-1)(Br)`
In this reaction , the oxidation number of bromine is increasing from 0 (in `Br_2`) to ` +1` (in `HBr`). as well as decreasing from 0 (in `Br_(2)`) to `-1` (in `HBr`). It is a disproportionation reaction as Br is oxidized as well as reduced.
