intermolecular forces - london dispersion forces

Question 1

name the 3 intermolecular forces

Answer 1

london dispersion forces
(induced dipole)

dipole-dipole forces

hydrogen bonding

Question 2

define intermolecular force

Answer 2

an attraction or repulsion between neighbouring molecules

Question 3

where can you see london dispersion forces?

Answer 3

between non-polar and polar

Question 4

describe london dispersion forces

Answer 4

when the electron distribution in a molecule become symmetrical

causing a temporary dipole

the positive + negative charge in the dipole can disturb electrons in a nearby molecule

Question 5

why are london dispersion forces called induced?

Answer 5

disturbing of electrons in nearby molecules repels the electrons

inducing a dipole in that molecule

Question 6

what happens to the temporary dipole and the induced dipole? (LDF)

Answer 6

the molecules from both dipoles attract each other

pulling the molecules together
