Which among the following compounds undergoes SN ^2 reaction fastly?

Correct answer

3

Step-by-step solution

Reactivity for SN ^2 reaction (a) aligned & Reactivity 1 steric hindrance of reactant & [ CH ₃- X >1^ >2^ >3^ Halide ] aligned (b) If alkyl group of substrates are same then Reactivity L.G. Ability [ R - I > R - Br > R - Cl > R - F ] thus I undergoes S _ N 2 reaction fastly
