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) Rhombic sulphur | (i) 393 K |
| (b) Monoclinic sulphur | (ii) 2.06 |
| (c) Boiling point of PH3 | (iii) Hydrogen bonding |
| (d) Boiling point of NH3 | (iv) Higher than PH3 |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-i, d-iii
D
a-i, b-iii, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
Rhombic sulphur has a melting point of 385.8 K (ii) and a specific gravity of 2.06. Monoclinic sulphur has a melting point of 393 K (i). PH3 has a lower boiling point than NH3 due to the absence of hydrogen bonding (iii), while NH3's boiling point is indeed higher (iv).
