Answer to Question #175811 in General Chemistry for Nicole

Question

Nitrogen atom in HCN is electron rich and the molecular dipole points in the direction of this atom.

1. Why does nitrogen become electron rich?

2. How will you describe the interaction among moleculesin terms of strength?

Answer 1

1)

Because nitrogen is a strongly electronegative (electron-attracting) element, the net result is to remove electronic charge from the ring, as just depicted in the canonical forms of pyridine.

2)

Dipole dipole forces
