Intermolecular Forces. Chemistry Jokes of the Day. Why did the white bear dissolve in water? Because it was polar. What do dipoles say in passing? "Have you got a moment?“ Why are chemists great for solving problems? They have all the solutions. . States of Matter .
Why do we need to know about intermolecular forces?
- Because these intermolecular forces are responsible for the existence of the liquid state and explained some unusual properties of liquids: i.e. Water - high boiling point
Strong: Covalent Bonding & Ionic Bonding
Medium Strength: Hydrogen Bond
Weak: Dipole-Dipole & London Dispersion
For Example: N2, H2, CH4
a higher Boiling
All of these properties are greatly depended on the strength of the intermolecular forces: DDF, LDF, H-bond.
