How do you know go about distinguishing what type of forces molecules have when interacting? How do you guys find it best to remember them, any tips? I tend to get confused between all the dipole forces. Thanks!
All molecules have London Dispersion Forces, and the strength of the LDF depends of the size of the atoms. Hydrogen bonds occur when an H is bonded to an N, O, or F. Nonpolar molecules can have LDF. Polar covalent molecules can have dipole-dipole and LDF. Ionic compounds can have ion-ion. Try to determine if the structure you are dealing with is non polar or polar, and then notice which bonds occur between polar molecules and which between non polar. Dipoles are associated with polar molecules.
