208 -- Which of the following statements is correct?
[A)] In nonpolar molecular substances, as molar mass increases, intermolecular forces increase.
[B)] Since the molar mass of $\mathrm{N_2}$ and $\mathrm{CO}$ are equal, $\mathrm{CO}$ has a boiling point closer to $\mathrm{N_2}$.
[C)] Water and hydrogen sulfide; both molecules have polar bonds and boiling points close to each other.
[D)] Since the molar mass of $\mathrm{F_2}$ is less than the molar mass of $\mathrm{HCl}$, the boiling point of $\mathrm{HCl}$ is higher than that of $\mathrm{F_2}$.
