Intermolecular Forces

Question 1

Intramolecular Forces

Answer 1

They are Covalent bonds which keep atoms clustered together within the molecule

Question 2

Dipole dipole forces

Answer 2

type of Intermolecular force
- Only in polar molecules
- Is the attraction of Polar molecules due to their weak electrostatic attraction between dipoles
- Increases melting & boiling point

Question 3

Dispersion Forces

Answer 3

intermolecular force
-Weakest force
- present in all molecules, mostly non polar
- Due to random movement of electrons within a molecule producing varying temporary dipole
Size of molecule increase = increase dispersion force

Question 4

Intermolecular Forces

Answer 4

An electrostatic force of attraction between molecules

Question 5

Hydrogen Bonding

Answer 5

-Strongest force
Attraction between a lone pair of electrons ( F, O or N atom) and hydrogen atom that is already covalently bonded to Fluorine, Oxygen and Nitrogen atom
