Consider the following compounds: H2S, H2Se, H2Te. The molecule with the highest boiling point is _, while the molecule with the highest vapor pressure is _.

Boiling point of any substnace is inverely proportional to its vapour pressure, and boilig point is directly proportional to the molecular mass of the substance.

In the given compounds H₂S, H₂Se and H₂Te molecular mass of Te is high and of Sulphur (S) is small. So the boiling point of H₂Te is highest and of H₂S is low so the vapor pressure of H₂S is highest.

Hence, H₂Te has the highest boiling point and H₂S has the highest vapor pressure.
