Question

Critical temperature for carbon dioxide and methane at 31.1 degree celsius and -81.9 degree celsius respectively . Which of these has stronger intermolecular forces and why ?

Answer 1

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.

⭐. Higher the crictical temperature more easily the gas can be liquified i.e greater are the inter molecular forces of attraction .

therefore , CO2 has stronger inter molecular forces than CH4.
