NEET Chemistry Preparation Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Ethanol dehydration at 443 K | (i) Ethene |
| (b) Ethanol dehydration at 413 K | (ii) Ethoxyethane |
| (c) Williamson's synthesis | (iii) Alkene formation |
| (d) Acidic dehydration of secondary alcohols | (iv) Not suitable |
A
a-i, b-ii, c-iv, d-iii
B
a-ii, b-i, c-iii, d-iv
C
a-ii, b-i, c-iv, d-iii
D
a-i, b-ii, c-iii, d-iv
Correct Answer
Option D
Detailed Explanation
Ethanol dehydration at 443 K primarily gives ethene, while at 413 K, ethoxyethane is formed. Williamson's synthesis is suitable for primary alcohols, and acidic dehydration of secondary alcohols is not suitable due to steric hindrance.
