h bonding and dipole dipole

Postby Elyssa Smith 4B » Tue Nov 19, 2019 1:39 pm

If a molecule has hydrogen bonding, does that automatically mean it has dipole dipole too?

Hydrogen bonding is actually a very specific type of dipole-dipole interaction, between and H-N, H-O, or H-F bond and the lone pair of another electronegative element. So in that sense, yes: if a molecule has hydrogen bonding, it technically has dipole-dipole interactions as well.

Yes, hydrogen bonding a type of dipole-dipole interaction.

A hydrogen bond is a dipole-dipole force but not all dipole-dipole forces are hydrogen bonds--- only when a H bonds with a highly electronegative atom (N,O,F). Hydrogen bonds are stronger than normal dipole-dipole forces.

Yes, a molecule with hydrogen bonding must also have dipole-dipole interactions.
