It would be great to be able to draw on these boards but such is not the case. Probably better for me to give you a site where the pictures can tell you. Post back if they pictures are not clear. Pick one of the following and click on it. The first one looks good to me.

Could someone explain dipole-dipole forces for me?

Dipole means two ends having opposite charge.A dipole is usually formed in a molecule in which one of the atoms is highly electronegative.For example HCl
Here Cl is highly electronegative which attracts the electrons present between H and Cl towards itself.As a result a negative charge develops on Cl and positive charge is formed towards H.
Now the when these dipoles interact,the positive pole of one dipole is attracted towards negative pole of other dipole.This attraction is called dipole-dipole force.
NOTE-Dotted line you see in picture given in above link shows dipole-dipole force.
