Chemistry-SN1 & SN2 Reactions

NEET Chemistry SN1 & SN2 Reactions Match the Following Question

Type: Match the Following-match the column-Easy-Class 12

Match Column-I with Column-II.

Column-I Column-II (a) SN1 reaction (i) Involves a carbocation intermediate (b) SN2 reaction (ii) Rate depends on two reactants (c) Primary halide (iii) Generally more reactive in SN2 (d) Tertiary halide (iv) Generally more reactive in SN1

Choose the correct matching:

A

a-i, b-ii, c-iii, d-iv

B

a-ii, b-i, c-iv, d-iii

C

a-i, b-iv, c-ii, d-iii

D

a-iv, b-iii, c-i, d-ii

Correct Answer

Option A

Detailed Explanation

In SN1 reactions, as stated in the NCERT content, the reaction involves a carbocation intermediate and follows first-order kinetics, thus the rate depends only on one reactant (tert-butyl bromide). In contrast, SN2 reactions involve a single concerted step where the rate depends on both the nucleophile and the substrate, making primary halides more reactive in SN2 reactions, and tertiary halides more reactive in SN1 reactions.
