Question

Which is the best description of behaviour of bromine in the reaction given below? $H_2O + Br_2 \to HBr + HOBr$

• A. Proton accepted only
• B. Both oxidised and reduced
• C. Oxidised only
• D. Reduced only

Answer 1

Answer: (B)

Both oxidised and reduced

Answer 2

In reaction, ${{H}_{2}}O+\overset{0}{{B}}\,{{r}_{2}}\xrightarrow[{}]{{}}HO\overset{+1}{{Br}}\,+H\overset{-1}{{Br}}\,$ The oxidation number of bromine increases from 0 to $+1$ and decreases from 0 to $-1,$ so due to this reason bromine is both oxidised as well as reduced in the above reaction.
