NEET Chemistry Preparation 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) Dehydration of ethanol (i) Williamson’s synthesis (b) Formation of ethoxyethane (ii) Higher temperature, alkene (c) Secondary alcohols (iii) Ether formation not suitable (d) Acidic conditions (iv) Alkene formation possible
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-ii, c-iii, d-i
D
a-iii, b-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
The dehydration of ethanol under acidic conditions can lead to the formation of an alkene or ether depending on the temperature and conditions, aligning with the correct pairings in option A. Ethoxyethane is formed at lower temperatures, while higher temperatures favor alkene formation.
