MCAT Organic Chemistry Exam Questions and Answers Instantaneous Dipole Moment - Answer-Exists in an otherwise nonpolar molecule. Occurs because the electrons in a bond move about the orbital and at any moment may not be distributed exactly between the two bonding atoms, even when the atoms are identical. London Dispersion Forces - Answer-Occur between two instantaneous dipoles; the weakest dipole-dipole force (vs. hydrogen bonds which are the strongest dipole-dipole forces). Wolff-Kishner...
