The intermolecular force found in hydrogen sulphide is hydrogen bonding. Hydrogen bonding is a type of dipole-dipole interaction that occurs when a hydrogen atom is bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine. In the case of hydrogen sulphide, the hydrogen atom is bonded to a sulphur atom, which is electronegative enough to create a partial positive charge on the hydrogen atom. This partial positive charge then interacts with the partial negative charge on the sulphur atom of another hydrogen sulphide molecule, creating a hydrogen bond.
