Chapter 11 Structure and nomenclature of organic compounds

Question 1

Dispersion forces

Answer 1

A very weak force of attraction between molecules caused by temporary dipoles induced in the molecules. The temporary dipoles are the result of random fluctuations in the electron density.

Question 2

Dipole-dipole attractions

Answer 2

A form of inter-molecular force that occurs between polar molecules where the positively-charged end of one molecule is attracted to the negatively-charged end of a neighbouring molecule.
