An alkyl halide reacts with metallic sodium in dry ether. The reaction is known as : In electrophilic substitution reaction of chlorobenzene, the chloro group: Which of the followings statements is/are incorrect? Polymerization of alkenes takes place through Assertion (A): The boiling points of alkyl halides decrease in the order:

RI > {R B r} > {R C I} > {R F}

.

Reason (R): The boiling points of alkyl chlorides, bromides and iodides are considerably higher than that of the hydrocarbon of comparable molecular mass. Friedel-Craft’s reaction of bromobenzene with methyl iodide gives:
