Critical temperature for carbon dioxide and methane are $31.1^{\circ} C$ and $-81.9^{\circ} C$ respectively. Which of these has stronger intermolecular forces and why?
(A) The critical temperature of a gas is a measure of the strength of intermolecular forces of attraction.
Higher critical temperature indicates that the gas can be liquefied more easily,which implies stronger intermolecular forces of attraction.
Since the critical temperature of $CO_2$ $(31.1^{\circ} C)$ is higher than that of $CH_4$ $(-81.9^{\circ} C)$,$CO_2$ has stronger intermolecular forces of attraction.
