b- Hofmann Rearrangement
Amides with no substituent on the nitrogen react with solutions of bromine or chlorine in sodium hydroxide to yield amines through loss of their carbonyl carbon by a reaction known as the Hofmann rearrangement

E- Oxidation of Toluene by KMnO4
Toluene is oxidized with alkaline KMnO4 followed by acidification to form benzoic acid. Other oxidising agents that can be used are acidic KMnO4 , acidic K2Cr2O7 and dil HNO3 etc
