Q. The correct order of normal boiling points of $O_2, N_2, NH_3$ and $CH_4$ for whom the values of van der Waals constant '$a$' are $1.360, 1.390, 4.170$ and $2.253\, L^2$ atm $mol^{-2}$ respectively, is:

Solution:

van der Waal's constant 'a' depicts the correction of intermolecular forces. Higher the value of ' $a$ ' stronger the intermolecular force. The order of normal boiling points : $O _{2}< N _{2}< CH _{4}< NH _{3}$.
