Question

Given below are two statements:

Statement I: The boiling point of hydrides of Group 16 elements follow the order

$\mathrm{H}_{2} \mathrm{O}>\mathrm{H}_{2} \mathrm{Te}>\mathrm{H}_{2} \mathrm{Se}>\mathrm{H}_{2} \mathrm{~S}$ .

Statement II: On the basis of molecular mass, $\mathrm{H}_{2} \mathrm{O}$ is expected to have lower boiling point than the

other members of the group but due to the presence of extensive H -bonding in

$\mathrm{H}_{2} \mathrm{O}$ , it has higher boiling point.

In the light of the above statements, choose the correct answer from the options given below:
