Assertion : Oxidation of 1-nitronaphthalene gives o -nitrophthalic acid whereas 1-amino naphthalene on oxidation gives phthalic acid. Reason: An amino group attached to the benzene ring makes it resistant to oxidation whereas nitro group makes the benzene ring susceptible to oxidation.

TestHub · Accepted Answer

An amino group increases the electron density in the benzene ring to which it is attached thereby making it susceptible to oxidation while a nitro group decreases the electron density in the benzene ring to which it is attached thereby making it resistant to oxidation. Instead, the other benzene ring gets oxidised giving $o$ -nitrophthalic acid as shown below :
