Critical temperature for CO_(2) and CH_(4) are 31.1^(@)C and -81.9^(@)

1.	Critical temperature for CO_(2) and CH_(4) are 31.1^(@)C and -81.9^(@)C respectively. Which of these has stronger intermolecular forces and why ?
Answer» Solution :Higher the CRITICAL temperature, more EASILY the gas can be liquefied, i.e., greater are the intermolecular forces of attraction. Hence, `CO_(2)` has STRONGER intermolecular forces than `CH_(4)`.
