MCQ
Benzene can:
- ADischarge colour of KMnO4
- BDischarge colour of bromine water
- CPolymerise
- DUndergo substitution reactions
Explanation:
"Benzene decolourise bromine water". Discharge colour of KMnO4. Both are incorrect and also it doesn't undergo polymerization.
Because it does not undergo addition reaction as it is highly saturated due to presence of electron cloud above and below it. (aromatic system is more stable)
But it undergo substitution reactions.
