NEET Chemistry Preparation Methods 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) Free radical halogenation | (i) Electrophilic substitution with aryls |
| (b) Sandmeyer’s reaction | (ii) Preparation of alkyl chloride |
| (c) Electrophilic substitution | (iii) Preparation of aryl halides |
| (d) Direct halogenation of alkanes | (iv) Formation of haloalkanes |
A
a-iv, b-iii, c-i, d-ii
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-iv, c-i, d-iii
D
a-iii, b-i, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
Free radical halogenation is a method used for the preparation of haloalkanes, while Sandmeyer’s reaction is specifically used for preparing aryl halides. Electrophilic substitution is indeed applicable to aryls. Direct halogenation of alkanes leads to the formation of haloalkanes.
