n-butyl benzene on oxidation will give:

A)  benzoic acid    

B)         butanoic acid

C)  benzyl alcohol  

D)         benzaldehyde

E)  4-phenyl butanoic acid

Correct Answer: A

Solution :

In the case of homologues of benzene the side chain irrespective of its length, is oxidised to a carboxyl group by means of oxidising agents like chromic acid, or potassium permanganate. Hence, n-butyl benzene on oxidation will give benzoic acid.
