Aryl halides can not be prepared by the reaction of aryl alcohols with

{PCl}_3, {PCl}_5

{SOCl}_2

because

View answer and explanation

Correct option: B

Carbon-oxygen bond in phenols has a partial double bond character.

Option B (Carbon-oxygen bond in phenols has a partial double bond character) is correct because the resonance in aryl alcohols (phenols) gives the C-O bond a partial double bond character, making it stronger and harder to break.

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:
