What is the bond polarity of {H_2}S ?

The molecule H₂S, hydrogen sulfide, is a polar molecule. It has a bent molecular geometry, similar to water (H₂O), with two hydrogen atoms bonded to a central sulfur atom.

The sulfur atom is more electronegative than hydrogen, which means it has a greater affinity for electrons. As a result, the sulfur atom pulls the shared electron pair in the covalent bonds closer to itself, creating a partial negative charge (δ-) on the sulfur atom and partial positive charges (δ+) on the hydrogen atoms.

The presence of these partial charges gives H₂S a net dipole moment, making it a polar molecule. The polarity of H₂S arises due to the unequal sharing of electrons between hydrogen and sulfur, resulting in a slightly positive and slightly negative region within the molecule.
