Strongest Intermolecular Force in Hydrogen Sulfide
In the case of hydrogen sulfide, the strongest intermolecular force
must be maintained by its force. In the case of hydrogen sulfide ($H_2S $), we want to study the strongest intermolecular force.
Looking at the structure of hydrogen sulfide, sulfur atoms and hydrogen atoms are connected by covalent bonds. Sulfur is more electronegative than hydrogen, so hydrogen-sulfur bonds are polar. However, the molecular configuration of hydrogen sulfide is V-shaped, although it is polar, it does not reach the ground step where hydrogen bonds can be formed.
Intermolecular forces are commonly van der Waals forces, which are further divided into dispersion forces, induction forces, and orientation forces. The dispersion force, due to the continuous movement of electrons in the molecule, causes the generation of the instantaneous dipole of the molecule. This instantaneous dipole induces the formation of induced dipoles in adjacent molecules, and then there is a mutual attraction force, and the greater the relative molecular mass, the stronger the dispersion force. Inductive force, when the polar molecule interacts with the non-polar molecule, the inherent dipole of the polar molecule causes the non-polar molecule to produce an induced dipole, and the two attract. The orientation force exists between the polar molecules, and the inherent dipole is oriented to each other.
For hydrogen sulfide, because it is a polar molecule, the induction force, the orientation force, and the dispersion force all exist. However, after consideration, the relative molecular mass of hydrogen sulfide is moderate, and the dispersion force accounts for a relatively large proportion of the intermolecular force.
In summary, the strongest intermolecular force in hydrogen sulfide is the dispersion force. Although invisible, this force has a crucial impact on the physical properties of hydrogen sulfide, such as melting point and solubility.
