Dipole moment

Vedclass · Answer

(D) The critical temperature of a substance depends on the strength of intermolecular forces. $H_2O$ is a polar molecule with a permanent dipole moment $(1.84 \ D)$,which leads to strong dipole-dipole interactions and hydrogen bonding. In contrast,$O_2$ is a non-polar molecule with a dipole moment of $0 \ D$,exhibiting only weak London dispersion forces. Therefore,$H_2O$ has a higher critical temperature than $O_2$.

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