Which is the best description of the berhaviour of bromine in the reaction given below?
$H_{2} O + B r_{2} \to H O B r + H B r$

Options:

Answer:

Solution:

$H_{2} O + \overset{0}{B r_{2}} \to \overset{+ 1}{H O B r} + \overset{- 1}{H B r}$
In the above reaction the oxidation number of $B r_{2}$ increases from zero (in $B r_{2}$ ) to +1 (in HOBr) and decreases from zero (in $B r_{2}$ ) to – 1 (in HBr). Thus $B r_{2}$ is oxidised as well as reduced and hence it is a redox reaction.
