Chemistry - Halogen Derivative Question with Solution | TestHub

Question Explanation:

Picking correct statements regarding ${\mathrm{S}}_{\mathrm{N}}1$ reaction readiness and conditions. Concept: ${\mathrm{S}}_{\mathrm{N}}1$ Reaction Factors

Solution: ${\mathrm{S}}_{\mathrm{N}}1$ readiness depends on carbocation stability (Resonance, Hyperconjugation). It is favored in polar protic solvents which solvate ions effectively.

(A) EWG at ortho and para Position increase aromatic nucleophilic substitution.

(B) is wrong as

is highly unstable.

(C) Same reason as ' $a$ '.

(D) ${\mathrm{S}}_{\mathrm{N}}1$ reaction occurs in polar protic solvent with high dielectric constant.

Final Answer:
