intermolecular forces problem

Postby halle young 4A » Wed Nov 13, 2019 9:25 pm

this is an in general question, but I am having trouble determining what dispersion forces are used when and if the molecule is polar or not (can't do the homework problems). Will we learn how to do these after completing sections 2E-F?

I believe you are referring to inter molecular forces, as dispersion forces are simply a type of IM forces. These will be gone over, but the general methodology for determining whether or not a molecule will be polar if the dipole moments in it do not cancel in terms of their vectors and a general rule is if there are lone pairs present it will be polar. Hope this helps!
