NEET Chemistry SN1 & SN2 Reactions Match the Following Question
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-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-iv, b-iii, c-i, d-ii
Correct Answer
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.
