Boiling Points of Group 16 Hydrides and Hydrogen Bonding

2024 1 question

1. Given below are two statements: Statement I: The boiling point of hydrides of Group 16 elements follow the order $H_2O > H_2Te > H_2Se > H_2S$. Statement II: On the basis of molecular mass, $H_2O$ is expected to have lower boiling point than the other members of the group but due to the presence of extensive H-bonding in $H_2O$, it has higher boiling point. In the light of the above statements, choose the correct answer from the options given below:
