Explanation / Answer

1. dipole-dipole force and Dispersion force Reason: In H2S there is electronegativity difference between the S and H so S having higher electronegativity will try to pull the electron of H. That' s they will behave as dipole. Whereas in H2Se the size of Se is larger then that of S so its electronegativity will not have same effect as of S. That's why there will be Dispersion force between H2Se.

2. Higher molar mass: Here Se and S are of the same group but down the group Molecular mass increases and as the molecular mass increase the dispersion force's strength increases.

3. Hydrogen Bonding. As the hydogen bonding occurs between (O, N, F) and hydrogen and H2O has Oxygen.

4. Stronger intermolecular forces: As the hydrogen bonding is much stronger than Dipole-Dipole interaction so here deciding factor will be strong intermolecular force.

Hope this would help you. Thanks for asking and have a nice day.
