SUMMARY
Hydrogen sulfide (H2S) is a polar molecule due to its bent molecular geometry, which results in a dipole moment of 0.97 D. Despite its polarity, H2S exhibits only weak dipole-dipole interactions and does not engage in hydrogen bonding like water, which has a dipole moment of 1.85 D. The electronegativity difference between sulfur and hydrogen is 0.38, indicating that while H2S is polar, it is not strongly polar. Consequently, H2S remains a gas at room temperature due to its weak intermolecular forces.
