consider the following compound: h2s indicate whether the molecule is polar, or not. give complete reasoning for your answer, including shape, electronegativity difference and the types of bonds present.

Answer

Explanation:

Step1: Determine bond - type

The electronegativity of H is 2.2 and of S is 2.58. The electronegativity difference $\Delta\chi=2.58 - 2.2=0.38$. Since $0<\Delta\chi<1.7$, the H - S bonds are polar covalent.

Step2: Determine molecular shape

S has 6 valence electrons and forms 2 bonds with H. There are 2 bonding pairs and 2 lone - pairs of electrons around the S atom. According to VSEPR theory, the molecular shape of $H_2S$ is bent.

Step3: Analyze polarity

In a bent molecule with polar bonds, the bond dipoles do not cancel out. The net dipole moment is non - zero.

Answer:

The $H_2S$ molecule is polar.
