Answer to Question #89575 in General Chemistry for Mel

Question

The boiling point of water is 100°C. State whether hydrogen sulfide has a stronger force of attraction between molecules. Explain your answer.

Answer 1

Hydrogen sulfide shows less force of interaction between molecules than water. This is due to the fact that the sulfur atom is larger than the oxygen atom and the negative charge in it is delocalized in a larger volume due to the brow decreases the dipole moment of the mollecule, this leads to the fact that the hydrogen bond between the molecules becomes weaker. In practice, this is expressed in a lower boiling point, viscosity, surface tension coefficient.
