Question

Of the following, ________ should have the highest critical temperature. Of the following, ________ should have the highest critical temperature. CH4 H2 CCl4 CBr4 CF4

Answer 1

Answer:

H2

Explanation:

Critical temperature is the temperature above which gas cannot be liquefied, regardless of the pressure applied.

Critical temperature directly depends on the force of attraction between atoms, it means stronger the force of higher will be the critical temperature. So, from the given options H2 should have the highest critical temperature because of high attractive forces due to H bonding.

Hence, the correct option is H2.
