View answer and explanation
Correct option: D
(ii) (i) (iii) (iv)
Option D ((ii) (i) (iii) (iv)) is correct because the SN2 reaction rate depends on steric hindrance and the stability of the transition state. Benzyl halides are more reactive than methyl halides, and substituted aryl halides are the least reactive.
