NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) 2-Bromo-2-methylbutane | (i) Reacts via SN2 mechanism |
| (b) 1-Bromopentane | (ii) Reacts via SN1 mechanism |
| (c) 1-Bromo-2,2-dimethylpropane | (iii) Less reactive in nucleophilic substitution |
| (d) 2-Bromopentane | (iv) More reactive in nucleophilic substitution |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-iv, c-i, d-iii
D
a-i, b-iv, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
2-Bromo-2-methylbutane reacts via the SN1 mechanism due to its tertiary carbon center, while 1-Bromopentane reacts via the SN2 mechanism due to being a primary halide. The reactivity in nucleophilic substitution decreases with steric hindrance, supporting the pairings in option A.
