Ring Flip: Final
If we are asked to draw a ring flip on the final should we include the boat conformation transition, or should we simply draw the two chair conformations?

Re: 2 Substituents on a Ring
Since it is in a ring structure, you are correct that the number will always be the same. Therefore it is the common practice of a ring with 2 substituents to give the first named substituent the lower number.

Re: Quiz 3 Winter 2017
For kinetics, what part of the book is on the quiz? Does "Reaction profiles, Arrhenius equation and calculating activation energies" mean that it is only 15.11 and 15.13, or will the rest of chapter 15 be on the quiz? Also, just to be clear, is Catalysis on there? Catalysis is included in...

If a nucleophile is identified by its desire for protons, are all molecules with negative charges then nucleophiles.

14C
Hey so I know that it will be hard to get spots in 14C like it was to get spots in 14B, and I was curious if Hardinger's policy for the waitlist was like Lavelle's. Lavelle told us when we were registering last quarter that if we made it on the waitlist we would get in the class, so I was curious if...

Single electrode redox
When oxidation and reduction reactions are run through a singular electrode that has a voltage applied across it it will run only one of the reaction at a time. What determines whether it goes through oxidation or reduction. Obviously the solution being used needs to be capable of going up or down. ...

entropy versus degenercy
So I'm just trying to clarify
Entropy (S) is the likelihood that a system will be in a certain state and degeneracy is the number of ways of achieving a given energy state. So for the certain state represented by S, W represents the number of ways of getting to the energy level of that formation?

I'm looking at the chapter 8 problems and need a little more clarification on open, closed, and isolated systems. Could someone give me another example of each of these systems that we haven't used yet?

Re: Isolated Systems [ENDORSED]
In this case it is saying it is the best example of an isolated system. While we know that over time it does lose heat, it in theory (if it is a quality thermos) acts as an isolated system that does not exchange heat or matter.

Clarification of pH versus pOH [ENDORSED]
So I just want to clarify...
If I were given a problem asking me to calculate the pOH value of something and I was given the concentration of H30+ I would calculate the pH and then subtract the calculated value rom 14.00 to get the pOH, correct?

Re: Amine
An amine is classified as an organic compound derived from ammonia (NH3) by replacing one of the hydrogen with an organic compound. For example, in en and dien, the H is replaced by a bond to a carbon molecule.

As far as MO theory goes there are not practice questions on the quiz that address it, but I thought I remembered it being included in things that would be on Quiz #3. I just wanted to see if anyone could give me a solid answer on whether MO would or would not be on Quiz #3.

Re: Electronegativity Difference
No, the number of molecules of each element should not have any effect. The electronegativity difference is for a specific bond, therefore it should only consider two of the molecules.

I assume we are expected to show work on our quiz responses, but I was curious if anyone had any idea to what degree we were expected to show work? For example, would I need to show how I came up with the molar mass for something, or can I simply just plug in the molar mass I calculated?

Where would Planck's constant be plugged in to?
Plugging in Planck's constant is not necessary. All the other steps they listed are correct, but Planck's constant is irrelevant in this problem.
