Interomolecular forces

Question 1

Three types of intermolecular forces

Answer 1

Permanent Dipole-Dipole
London forces
Hydrogen bonding

Question 2

Weakest to strongest intermolecular forces

Answer 2

London force , permanent dipole-dipole and then hydrogen bonding

Question 3

In hydrogen bonding what must the line be like

Answer 3

The lines must be parallel to the bond line and touching the outer electrons on the adjacent atom

Question 4

How does hydrogen bonding work

Answer 4

Hydrogen bonding works by the hydrogen atoms becoming positive while the adjacent atom it is bonded to being negative . Another of the same compound is joined up with the hydrogen atom now being joined up to the positive adjacent atom

Question 5

How does london forces work

Answer 5

Electrons spread in a random movement and temporarily create an induced dip like effect by one side of the atom having more electrons than the other making it more negative . This then repels electrons on the adjacent atom making it have the same effect and starts a chain reaction. This makes a london force between the negative side of one atom and the positive side of the other atom. This is the weakest force

Question 6

How does a permanent dipole-dipole bond work

Answer 6

Between two polar molecules and it’s between negative and positive

Question 7

Why do bonds with more electrons have higher boiling points

Answer 7

More and stronger london forces between atoms
