Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Ozone | (i) +142 kJ mol –1 |
| (b) Dioxygen | (ii) Pale blue gas |
| (c) Hydrogen peroxide | (iii) Decomposes to dioxygen |
| (d) Nitrogen | (iv) Does not form pentahalide |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Ozone is known to have an endothermic formation enthalpy of +142 kJ mol –1 and appears as a pale blue gas. Dioxygen is a gas that can be produced from hydrogen peroxide, which decomposes into dioxygen. Nitrogen does not form pentahalides due to its inability to expand its covalence.
