Question

The geometry of ${\mathrm{H}}_2\mathrm{S}$ and its dipole moment are______.

• A. Bent
• B. $0.95$

Answer 1

Geometry of ${\mathrm{H}}_2\mathrm{S}$

• The structure of ${\mathrm{H}}_2\mathrm{S}$ is as follows:-

• In the structure, two bond pairs and two lone pairs are present.
• So, the geometry of ${\mathrm{H}}_2\mathrm{S}$ is distorted tetrahedral or bent.
• The hybridization of ${\mathrm{H}}_2\mathrm{S}$ is ${\mathrm{sp}}^3$.

Dipole moment

• “It is the product of the magnitude of the charge and the distance between the centers of positive and negative charges.”
• The dipole moment of ${\mathrm{H}}_2\mathrm{S}$ is $0.95$ because the electronegativity of sulfur is greater than hydrogen, making the molecule polar.

Hence, the geometry of ${\mathrm{H}}_2\mathrm{S}$ and its dipole moment are bent and $0.95$.
