Question

Critical temprature for co2 and ch4 are 31.1 degree celcius and -81.9 degree cecius respectively. which of these has stronger intermolecular forces and why ?

Answer 1

critical temperature directly proportional to intermolecular forces

so
in CO2 stronger intermolecular force .

Answer 2

Hello!!

_________________________________

$\Huge{\mathfrak{\blue{\underline{ANSWER}}}}$

➡️If the critical temp of a gas is higher then it is easier to liquefy.

➡️That is the intermolecular forces of attraction among the molecules of gas are directly proportional to its critical temp.

➡️Therefore, in CO2 intermolecular forces of attraction are stronger.
