Chemistry - Halogen Derivative Question with Solution | TestHub

Question Explanation: Selecting correct ${\mathrm{S}}_{\mathrm{N}}2$ reactivity statements. Concept: ${\mathrm{S}}_{\mathrm{N}}2$ Steric and Electronic Effects

(a) For ${\mathrm{S}}_{\mathrm{N}}2$

$1^{\circ }\mathrm{RX}$ reacts faster.

(b) For ${\mathrm{S}}_{\mathrm{N}}2$

$RBr$ reacts as faster rate as Br is better leaving group.

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

(d) Aryl halides react slowly than RX towards nucleophilic substitution reaction.

Final Answer:
