What happens when
i. 2-Nitropropane boiled with HCl
ii. Nitrobenzene electrolytic reduction in strongly acidic medium.

Explanation

i. 2-Nitropropane boiled with HCl: 2-nitropropane upon hydrolysis with boiling HCl give a ketone (2-propanone) and nitrous oxide.

ii. Nitrobenezen electrolytic reduction in strongly acidic medium: Electrolytic reduction of nitrobenzene in weakly acidic medium gives aniline but in strongly acidic medium, it gives p-aminophenol obviously through the acid - catalysed rearrangement of the initially formed phenylhydroxylamine.
