Amongst

\text{H}_2\text{O}

\text{H}_2\text{S}

\text{H}_2\text{Se}

and

\text{H}_2\text{Te}

, the one with the highest boiling point is: (1)

\text{H}_2\text{O}

because of H-bonding (2)

\text{H}_2\text{Te}

because of higher molar mass (3)

\text{H}_2\text{S}

because of H-bonding (4)

\text{H}_2\text{Se}

because of lower molar mass
