What type of intermolecular forces exist in NH3 and H2S? dispersion forces, dispersion forces and H-bond, dispersion forces & dipole-dipole forces Solution In NH 3 ,intermolecular forces present are hydrogen bonds . The hydrogen bonds are many magnitudes stronger than other intermolecular forces in NH 3 . In H 2 S , Sulfur atom have 6 valency electrons and hydrogen atoms have 2 valence electrons. The central sulfur atoms has 4 entities around it. Two hydrogen atoms, and two lone non-bonding electron pairs. According to VSEPR theory, this means that the shape of the molecule is bent and because of the asymmetrical shape, the molecule is polar.The intermolecular force which polar molecules take part in are d ipole-dipole forces . .

1. What type of intermolecular forces exist in NH3 and H2S?
dispersion forces, dispersion forces and H-bond, dispersion forces & dipole-dipole forces
Solution
In NH 3 ,intermolecular forces present are hydrogen bonds . The hydrogen bonds are many
magnitudes stronger than other intermolecular forces in NH 3 .
In H 2 S , Sulfur atom have 6 valency electrons and hydrogen atoms have 2 valence electrons.
The central sulfur atoms has 4 entities around it. Two hydrogen atoms, and two lone non-
bonding electron pairs. According to VSEPR theory, this means that the shape of the molecule is
bent and because of the asymmetrical shape, the molecule is polar.The intermolecular force
which polar molecules take part in are d ipole-dipole forces .
