Intermolecular Forces

Question 1

Dipole dipole

Answer 1

When two polar encounter each other, the positive side of the one is attracted to the negative side of the other one. These interactions decrease rapidly as distance between molecules grow,

Question 2

What is a spwecisl case of dipole dipole forces

Answer 2

Hydrogen bonds. They are much stronger

Question 3

Dipole induced dipoles

Answer 3

Oxygen dissolves in water to a very small extent. Dipole induced dipole occurs when a polar molecule is brought close to a non-polar molecule. The negative side of the dipole repels the electrons in the non-polar molecule, making it polar. It is called polarization. The more electrons a molecule has, the more easily electrons can be polarized.

Question 4

Instantaneous dipole (London forces)

Answer 4

Occurs between two non-polar molecule. When the lecterns find themselves on the same side of each molecule, it formats a temporary dipole. This allows them to attract.
