Difference b/w melting point of h2o and h2s 1
Answers
Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
Melting point: -85.5 oC
Boiling point: -60.7 oC

Oxygen is more polar than Sulfur. Therefore, the Hydrogen Oxygen bond is more polar than the Hydrogen Sulfur bond. H20 has stronger intermolecular dipole--dipole interaction because of the greater polarity (or a hydrogen bond). Because of the stronger intermolecular interaction H20 is more stable and exists as a liquid.
H2S is bent, and bent at a smaller angle than is water. The bond angle in water is about 105 degrees which is predicated on the tetrahedral bond angle (109.5). But in H2S the bond angle is around 92 degrees. Both molecules are polar and exhibit dipole-dipole attractions, but in addition, water exhibits stronger hydrogen bonding.
