Vedclass · Answer

(D) Water is a polar molecule with a dipole moment $\mu = 1.84 \ D$,whereas $O_2$ is a non-polar molecule with $\mu = 0$. Due to the presence of a permanent dipole moment,water molecules experience stronger intermolecular dipole-dipole forces (and hydrogen bonding) compared to the weak London dispersion forces in $O_2$. Stronger intermolecular forces lead to a higher critical temperature.

The critical temperature of water is higher than that of $O_2$ because the $H_2O$ molecule has -
