Sulfur Compounds | MCQs

Explanation

Hydrogen sulphide gas is a naturally occurring chemical.

The gas has a characteristic rotten egg odor at low concentrations.

Hydrogen sulphide gas (H 2 S) is a colorless gas

Hydrogen sulphide is produced by reacting a metal sulphide (Ferrous sulphide) with a dilute acid (Sulphuric acid).

The element responsible for the rotten egg-like smell of Hydrogen sulphide is Sulphur (S).

Explanation

The molecular Geometry of SF6 (sulfur hexafluoride) is octahedral. 

In this molecule, the central atom i.e. sulphur has a total of six electrons in its valence shell

And in the molecule, we have six fluorine atoms so it shares one electron with each fluorine atom.

So this molecule has six bond pairs and no lone pair.

So its structure is octahedral

The bond angles in sulfur hexafluoride molecules are 90A∘ and 180A∘.

Explanation

In SF6 (sulfur hexafluoride), the central sulfur atom is bonded to six fluorine atoms in an octahedral arrangement. This results in two types of bond angles:

• The F-S-F bond angles in the equatorial plane are 90°
• The F-S-F bond angles between the equatorial and axial fluorine atoms are 180°
