3 Types of Van der Waals Forces

Answer 26

1) dipole-dipole 2) dipole-induced dipole 3) dispersion

Question 27

Two polar molecules align so that OPPOSITE CHARGES are matched (electrostatic attraction)

Answer 27

Dipole-Dipole

Question 28

A dipole can induce (cause) a temporary dipole to form in a non- polar molecule. Then molecules line up to match opposite charges

Answer 28

Dipole-Induced Dipole

Question 29

A temporary dipole forms in a non- polar molecule which leads to a temporary dipole to form in ANOTHER non-polar molecule.
