A hydrocarbon (A) exhibits a maximum of three structural isomers. Of these, the straight chain isomer on reacting with chlorine in the presence of UV. light gives compounds B and C. These compounds, on treatment with alcoholic KOH, form compounds D, E and F. The most stable products out of D, E and F, on reaction with HBr, forms G. The compound G reacts with NaI in the presence of dry acetone forming H.
Identify the compounds A − H. Write the reactions involved. Also name the reaction for the conversion of G to H.
