What is the difference between dispersion forces and dipole- dipole forces?

Answer 1

Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation

Answer 2

Dipole-dipole forces exist between permanent dipoles; dispersion forces exist between temporary dipoles.

Answer 3

i think that it is because there is a greater difference in electronegativity in hydrogen bonds then in dipole-dipole forces

Answer 4

dipole dipole occur between partial charges of the atoms in polar molecules

dispersion forces occur between nonpolar molecules

Answer 5

London dispersion forces are caused by instantaneous dipole- dipole interactions and the more electrons thare are the more these can occur. Larger molecules tend to have more electrons

Answer 6

dispersion forces are due to induced dipole in oyher atom due to first it is proportion to 1/r to the pover 6 dipole attraction is due to + and - charges on atom total or partial
