Hydrogen sulfide is a chemical compound with the formula H 2 S. It is a colorless chalcogen-hydride gas , and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs . [ 11 ]
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
The structure of hydrogen disulfide is similar to that of hydrogen peroxide, with C 2 point group symmetry. Both molecules are distinctly nonplanar. The dihedral angle between the H a −S−S and S−S−H b planes is 90.6°, compared with 111.5° in H 2 O 2. The H−S−S bond angle is 92°, close to 90° for unhybridized divalent sulfur. [1]
Formula Melting point (°C) Boiling point (°C) CAS number H 2 S: Hydrogen sulfide is a very toxic and corrosive gas characterised by a typical odour of "rotten egg". −85.7: −60.20: 7783-06-4: CdS: Cadmium sulfide can be used in photocells. 1750: 1306-23-6: Calcium polysulfide ("lime sulfur") is a traditional fungicide in gardening.

Hydrogen sulfide (H 2 S) too has a C 2v symmetry with 8 valence electrons but the bending angle is only 92°. As reflected in its photoelectron spectrum as compared to water the 5a 1 MO (corresponding to the 3a 1 MO in water) is stabilised (improved overlap) and the 2b 2 MO (corresponding to the 1b 2 MO in water) is destabilized (poorer overlap).
Amid the barrage of insults and smack talk were temporary moments of rapprochement between the 39 th and the 45 th presidents.. During Trump’s first term, Carter occasionally came to his defense.
Sodium hydrosulfide is the chemical compound with the formula NaSH. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless.
