NEET Chemistry SN1 & SN2 Reactions Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) SN1 Reaction | (i) Polar protic solvent |
| (b) SN2 Reaction | (ii) Primary halide reactivity |
| (c) Carbocation stability | (iii) Secondary halide reactivity |
| (d) Rate of reaction | (iv) Tertiary halide reactivity |
A
a-i, b-ii, c-iv, d-iii
B
a-ii, b-i, c-iv, d-iii
C
a-i, b-iii, c-ii, d-iv
D
a-iv, b-ii, c-i, d-iii
Correct Answer
Option A
Detailed Explanation
In SN1 reactions, the rate depends solely on the concentration of the substrate, typically requiring polar protic solvents for stability of the carbocation (Chunk 2). In contrast, SN2 reactions exhibit higher reactivity for primary halides due to steric factors (Chunk 2).
