is the atomic number of AI
Answer:
a) B
b) A
c) B
d) A
Explanation:
If the strength of an inter-molecular force increases, then
vapour pressure decreases and boiling point increases
- Hence, B is a gas at 300 mmHg due to its low boiling point
- A has a higher boiling point because of its strong inter-molecular forces
- B has weaker inter-molecular forces due to its higher vapour pressure
- A has higher heat of vaporization, because it has strong inter-molecular forces
