MCQ
Which is the best description of the behaviour of bromine in the reaction given below ${H_2}O + B{r_2} \to HOBr + HBr$
- AOxidised only
- BReduced only
- CProton acceptor only
- ✓Both oxidised and reduced
✓
Answer
Correct option: D.
Both oxidised and reduced
(d) ${H_2}O + \mathop {B{r_2}}\limits_0 \to \,\mathop {HOBr}\limits_{ + 1} + \mathop {HBr}\limits_{ - 1} $
In the above reaction the oxidation number of $B{r_2}$ increases from zero (in $B{r_2}$) to $+1$ (in $HOBr$) and decrease from zero ($B{r_2}$) to $-1$ (in $HBr$). Thus $B{r_2}$ is oxidised as well as reduced & hence it is a redox reaction.
