Amongst ${\mathrm{H}}_2\mathrm{O},{\mathrm{H}}_2\mathrm{S},{\mathrm{H}}_2\mathrm{Se}\text{ and }{\mathrm{H}}_2\mathrm{Te}$, the one with the highest boiling point is

The boiling point of a compound depends on various factors, including intermolecular forces, molecular weight, and polarity.

Out of the given options, water (H₂O) has the highest boiling point. This is because water is a polar molecule with hydrogen bonding between the molecules. Hydrogen bonding is a strong intermolecular force that requires a large amount of energy to break the bonds between the molecules. In comparison, the other hydrides, H₂S, H₂Se, and H₂Te, are non-polar molecules and do not have hydrogen bonding. Therefore, they have lower boiling points than water.
