How to Distinguished between ethyl chloride and chlorobenzene?

Hey student
see the basic difference in these compounds is one is aromatic and the other one is simple alkyl halide
So the aryl halide will give all the reactions of benzene like chlorination, sulphonation etc whereas the other one will not give those corresponding reactions

Treat both ethyl chloride and chlorobenzene with aq. KOH followed by reaction with NaOH and I2(Iodoform Reaction).The test-tube containing ethyl chloride on treatment with KOH gives primary alcohol which later on undergoes iodoform reaction.
