Hydrogen bond is more strong than Van Der Waals Force(Present in H2S), so H20 is more stable. During boiling, one has to break the bonds and hence greater amount of energy is required in the case of H20 since it is more stable and has a higher boiling point.
Hence, the correct option is (d).

The high boiling point of water compared to hydrogen sulphide or hydr...
Explanation:
The high boiling point of water compared to hydrogen sulphide or hydrogen chloride is due to hydrogen bonding. Hydrogen bonding is a special type of intermolecular force that occurs between a hydrogen atom in a polar bond and an electronegative atom (usually oxygen, nitrogen, or fluorine) on a neighboring molecule. The attraction between the hydrogen atom and the electronegative atom creates a dipole-dipole interaction that is stronger than the typical van der Waals forces that occur between non-polar molecules.
Under normal conditions, water molecules are held together by hydrogen bonds, which results in a higher boiling point compared to hydrogen sulphide or hydrogen chloride. The hydrogen bonding in water is stronger than the van der Waals forces in hydrogen sulphide or hydrogen chloride. This means that more energy is required to break the hydrogen bonds between water molecules, and as a result, water has a higher boiling point.
In summary, the high boiling point of water compared to hydrogen sulphide or hydrogen chloride is due to the presence of hydrogen bonding between water molecules, which is stronger than the van der Waals forces present in hydrogen sulphide or hydrogen chloride.
