The intermolecular forces that exist among the molecules of nh3 gas are?

The intermolecular forces that exist among the molecules of nh3 gas are – dipole dipole forces and hydrogen bonding.

Now, we will discuss about it. let’s know about both the forces.

(a) dipole-dipole forces

(b) hydrogen bonding

(a) Dipole-Dipole forces:

Its dipole dipole intermolecular forces because of electro negative atom nitrogen and hydrogen. dipole dipole intermolecular forces occur between nh3 molecules because hydrogen bonding occur between nh3 molecules because hydrogen (H) are directly attached with high electronegative atom such as nitrogen (N). therefore, we can say that, nh3 intermolecular forces has dipole dipole forces and hydrogen bonding. dipole-dipole intraction are attracted among polarized molecules. we know that polarized molecules has two poles partial positive pole and partial negative pole. therefore it is called dipole. dipole dipole intraction occur between two polarized molecules or between two polarized dipole.

Consider the one dipole, it has two pole partial positive pole and partial negative poles. consider another dipole it has also two poles, partial positive pole and partial negative poles, we has two dipoles. So, the negative pole of one molecules attracted the positive pole of another molecules. due to this attractive forces are produces. this attractive forces is called dipole dipole intraction.

(b) Hydrogen bonding:

• Hydrogen attached to an element with high electronegative atom such as, N, O, F.

• the element has at least one loan pair electron.

Yes, it is absolutely true, hydrogen bonding occur between nh3 molecules because hydrogen (H) are directly attached with high electronegative atom such as nitrogen (N). and we know that, if any molecules bound to highly electronegative elements such as, N, O, and F then it make hydrogen bonding between molecules due to large difference of electronegativity. it mean, nitrogen is highly electronegative atom compare with hydrogen.
