Difference between Dipole-Dipole and Dipole-Induced dipole?

Postby Mario Reyes 1C » Sun May 20, 2018 2:07 pm

In my notes I have both these examples with H-F H-F for dipole-dipole and H-Cl N-N(triple bond) for dipole-induced dipole. What is the difference between these two?

H-F is already a dipole, as H is delta positive and F is delta negative.

N triple bond N is naturally equally charged, given N has the N charge as N. But, in the presence of H-Cl, a dipole because H is delta positive and Cl is delta negative, there is a slight pull on the charge of the Ns, making one slightly delta positive and the other slightly delta negative. This dipole is induced because of the presence of a nearby dipole.

H-F already has dipoles, so in H-F H-F the negative dipole of F interacts with the positive H on the other molecule in a dipole-dipole interaction.

In H-Cl N-N, N-N is neutral (has no dipoles) while H-Cl is positive at H and negative at Cl. The dipoles in H-Cl attract/repel electrons in N-N and cause dipoles, resulting in a dipole-induced dipole
