Aryl halides doesn't undergo nucleophili...

Aryl halides doesn't undergo nucleophilic substitution reactions under ordinary conditions because of
1. approach nucleophilie is retarded
2. carbon carrying halogen atoms is `sp^(3)` - hybridised
3. the substrate molecule is destabilised due to resonance
4. partial double bond character between carbon and halogen

A

2 and 4 only

B

1 and 4 only

C

2 and 3 only

D

2, 3 and 4 only

Text Solution

Verified by Experts

The correct Answer is:
B

Because of the +R effect of halogen atom , C - X bond of aryl halide has some double bond character, hence it is inert towards nucleophile and approach of nucleophile is retarded.

Assertion : Aryl halides undergo nucleophilic substitution with ease Reason : Carbon-halogen bond in aryl halides has partial double bond character.

Assertion: Aryl halides are highly reactive towards nucleophilic substitution reactions. Reason : In case of haloarenes, halogen atom is attached to sp hybridised carbon atom.
