Benzene resists addition reactions because that would involve breaking the delocalisation and losing that stability.
An alkylbenzene is simply a benzene ring with an alkyl group attached to it. ... Alkyl groups are usually fairly resistant to oxidation. However, when they are attached to a benzene ring, they are easily oxidised by an alkaline solution of potassium manganate($VII$) (potassium permanganate).
