lol wow that makes up most of the high markers, you should probably learn those quickly :P

Where can I find them O.O

I know Halogenoalkane reactions and Alcohol reactions (words)

e.g. Halogenoalkane + Aqueous NaOH >>> Alcohol + NaX
Nucleophilic Substitution

But I wouldnt be able to apply it to a real life question and I dont know how to draw it either.

Permenant dipole is when the electrons are shared unequally between the two atoms bonded together in a covalent bond. because there is a large difference in electronegativity. Basically the more electronegative molecule will pull the electrons towards itself.

Van der Waal forces
Permanent dipole dipole interaction
Hydrogen bonds
Positive and negative charges on polar molecules cause weak electrostatic forces of attraction between molecules.These are permanent dipole dipole interactions.
