NEET2004ChemistryRedox ReactionsActual
Which is the best description of the behaviour of bromine in the reaction given below? H ₂ O + Br ₂ HOBr + HBr
Options
- AProton acceptor only
- BBoth oxidised and reduced
- COxidised only
- DReduced only
Correct answer
B. Both oxidised and reduced
Step-by-step solution
In the given reaction, the oxidation number of bromine increases from 0 to +1 and decreases from 0 to -1 . Due to this reason bromine is both oxidised as well as reduced. : H ₂ O + 0 Br ₂ HOBr + HBr ⁻¹ Caution Some students understood that the given reaction is redox reaction, but confuse with fact that redox reaction is the reaction in both oxidation and reduction occurs.
