Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The correct order of intermolecular force of attraction is as follows: Nitrogen < Mercury < Chalk < Iron.
Explanation: As we know, more the distance between the particles, lesser is the force of attraction between them. Nitrogen is a gas at room temperature. So, its particles have more space and less attraction between them than a solid.
Mercury is liquid at room temperature. So, its particles have comparatively more space and less attraction between them, than a solid.
Chalk piece can be easily broken because its particles have weaker force of attraction than that of iron.
