Dispersion

Will we have to know about dispersion and induced dipole for test 2? Or is it only london forces, dipole-dipole, and hydrogen bonding?

Dipole Moment

Whenever the dipole moments don't cancel can we assume that it is a polar molecule.

Re: Grading

I believe he doesn't make the curve until after the final so it changes each quarter but I'm hoping there's some type of curve because that's not a great average.

Re: Test 2

You should draw the most stable Lewis structure when doing calculating the bond angle.

Re: Quantum Numbers

There was also a question: How many electrons can have the following quantum numbers in an atom?
a) n=5, l=3, ml= -1 and the answer was 2 electrons
Can anyone explain why the answer is 2 electrons and not 14 since l corresponds to f orbital and f orbital can hold 14 electrons?

When studying by doing practice problems from the textbook, how do you guys check if your answers are correct? For me many times I may think I got the correct answer when I really didn't.
