NEET Chemistry Preparation Methods Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Free radical halogenation (i) Electrophilic substitution in the presence of Lewis acid (b) Sandmeyer’s reaction (ii) Reaction of alcohol with hydrogen chloride (c) Preparation of aryl halides (iii) Reaction of alkanes with halogens (d) Preparation of alkyl halides (iv) Reaction of aromatic amines with halogens
Choose the correct matching:
a-iii, b-iv, c-i, d-ii
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
The free radical halogenation involves the reaction of alkanes with halogens, resulting in alkyl halides. Sandmeyer’s reaction is used for preparing aryl halides from aromatic amines. The electrophilic substitution is a method to prepare aryl halides in the presence of a Lewis acid, and the preparation of alkyl halides can occur through the reaction of alcohols with hydrogen chloride.
