Answer 1

g. ) Correct . Because - NO2 is an electron withdrawing group, so it directs new electrophile to wards meta position.

H) No such reaction occurrs

I) Corrrect. Any length of alkyl group on benzene ring is oxidised in the presence of KMnO4 to carboxylic acid to form corresponding benzoic acid.

J) INCORRECT.

Here -CF3 is electron withdrawing which directs towards meta position and - CH3 is electron donating which directs toward otho and para position.

The corrective effect of -CF3 nad - CH3 directs the next electrophile towards prtho to - CH3 group and meta to - CF3 group.
