Intermolecular Forces

Question 1

London dispersion forces

Answer 1

Weakest of the 3, usually form between nonpolar molecules, electrons between 2 molecules are pushed apart, allowing for brief polarity, more electrons = more strength

Question 2

Dipole- Dipole interactions

Answer 2

Attraction between positive pole of one molecule with the negative of another, for polar compounds, harder to melt and boil compared to London

Question 3

Hydrogen bond

Answer 3

Special type of dipole, form between H ( bonded to O or N) and an O or N on another molecule
