Re: Saying Thank You to Dr. Lavelle

Thank you Dr. Lavelle for reminding me why I love chemistry with all of the math and concepts that go into it. It's been nice having consistency in at least one professor for the past two quarters. Your work is greatly appreciated.

Re: Transition states

If you're talking about an electrophillic addition reaction mechanism, there are two transition states.

Re: Cholesterol example on page 84 of CR

I believe that all of the carbons in the example have four bonds; the extra hydrogens just aren't shown on the molecule. It's very rare that C will only have two or three bonds.

Re: Quiz 3 Prep (3rd Prep) #1

How can you know whether a ligand is a monodentate or bidentate etc? Other than just memorizing? To be honest, I don't think there is any other way to know other than memorizing. If there is, I feel like it's beyond the scope of the class. I would just say memorize the few that are bidentates; then...

Re: Quiz 3 Prep (3rd Prep) #1

No, you don't count the H 2 O when counting the coordination number. Remember: number of bonds = coordination number For the first coordination compound, the coordination number would be 5. Oxalato (ox) is a bidentate so it has two bonds; carbonyl (CO) is a monodentate (one bond) but because there ...

Resonance and Electrons [ENDORSED]

So in lecture, Lavelle mentioned that electrons involved in resonance structures are delocalized. What exactly does localized/delocalized electrons mean?

Re: Unit Clarification [ENDORSED]

I believe your answer would be in x mol Cl- but while you're solving the problem you're finding x mol Cl based off the reaction equation given (I hope this makes sense).
