Dipole-Dipole Attraction
DIPOLE-DIPOLE ATTRACTION: When two dipoles attract
A DIPOLE is a POLAR MOLECULE: a molecule that’s asymmetrical. Two dipoles (asymmetrical molecules) can bond through DIPOLE ATTRACTION. The positive charge of one dipole attracts the negative charge of the other dipole.
Dipole (di pole):
Di means
