Why is H2S polar?
Understand the Problem
The question is asking for the reason behind the polarity of the hydrogen sulfide molecule (H2S). This involves understanding the molecular structure and the electronegativity of the atoms involved, specifically how the arrangement of hydrogen and sulfur atoms contributes to the overall polarity of the molecule.
Answer
H2S is slightly polar.
H2S is a slightly polar molecule due to its bent shape and the small electronegativity difference between hydrogen and sulfur, resulting in a non-zero dipole moment.
Answer for screen readers
H2S is a slightly polar molecule due to its bent shape and the small electronegativity difference between hydrogen and sulfur, resulting in a non-zero dipole moment.
More Information
Polarity in molecules like H2S arises due to their geometric structure and differences in electronegativity of the bonded atoms.
Tips
Common mistakes include assuming non-polarity due purely to symmetrical Lewis structures, ignoring the importance of the 3-D molecular shape.
