S-I: Styrene on reaction with

{HBr}

gives 1-bromo-1-phenylethane.

S-II: Benzyl radical is more stable than alkyl radical.

View answer and explanation

Correct option: A

Both S-I and S-II are correct

Option D is correct. S-I is wrong because Styrene on reaction with HBr gives 1-bromo-2-phenylethane, and S-II is correct because the benzyl radical is more stable than the alkyl radical due to resonance.

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:
