Question

2. If the critical temperature for carbon dioxide and methane are 31.10C and – 81.90C

respectively, then which of these has strong intermolecular forces? Give reason.

Answer 1

it means more the critical temperature more will be the liquification of the gas. That is its having strong intermolecular forces.
Here the critical temperature for carbon dioxide and methane are 31.10 0C and – 81.9 0C.
Carbondioxide is easily liquifiable that means its having strong intermolecular forces.
