Bonding in Hydrogen Sulfide
Bonding of hydrogen sulfide
Sulfur and hydrogen can form hydrogen sulfide. Sulfur, with hexavalent electrons, wants to obtain two electrons to form a stable octet. Hydrogen, with only one electron, is willing to lose and stabilize.
When sulfur and hydrogen combine, sulfur, with its two solitary pairs of electrons, and the single electrons of the dihydrogen atom each form a shared electron pair, which is a covalent bond. In this way, sulfur has eight electrons around it, and hydrogen also reaches the stable state of two electrons.
The molecular structure of hydrogen sulfide is angular. The sulfur occupies the center, and the dihydrogen separates the two sides. Due to the repulsive force of the solitary pairs of sulfur electrons on the bonding electron pairs, the hydrogen-sulfur-hydrogen bond angle is non-linear, about 92.1 °. This angular structure also affects many physical properties of hydrogen sulfide, such as polarity. The formation of
covalent bonds gives hydrogen sulfide specific chemical properties, and its stability and reactivity are closely related to the bonding method. Looking at its bonding, we can know the microstructure of the substance, which is the key to understanding its macroscopic properties.
