Chp 6 6.3/6.4 Intermolecular Forces

Question 1

Name the 3 intermolecular forces

Answer 1

Induced dipole dipole
Permanent dipole dipole
Hydrogen bonding

Question 2

How does induced dipole dipole forces work?

Answer 2

Electron clouds instantly move all the time making some parts of the atom opposite charges which will attract atoms doing the same

Question 3

What factors affect induced dipole dipole forces?

Answer 3

More electrons
Bigger atomic radius

Question 4

What are permanent dipole dipole forces?

Answer 4

The force between 2 polar molecules

Question 5

Which of induced dipole dipole and permanent dipole dipole forces are the strongest?

Answer 5

Permanent dipole dipole forces

Question 6

What is a hydrogen bond and which atoms are it between?

Answer 6

The bond between a hydrogen and either a nitrogen/oxygen/fluorine

Question 7

Are hydrogen bonds strong or weak?

Answer 7

Strong

Question 8

Why does hydrogen bonding only occur in the atoms N, O, H?

Answer 8

They are all highly electronegative
All have strong Pdd forces
