Re: Newman Projections for Cyclohexanes

Google cyclohexane Newman projection and it's the first image result. It looks like two Newman projections joined together, but I don't think we need to know that for the exam. I hope not.

Functional Group Numbers on Cycloalkanes

When assigning numbers to the substituents on a cycloalkane, or any cyclic structure, do the numbers have to be ordered clockwise? I didn't think this was true, but there are a few practice quiz problems that suggest this.

Friedal-Crafts Alkylation Book Example

In the the Friedal-Crafts alkylation example from the book, where does the Cl- given off at the end go? Or is that not important?

Re: deciding which cell is the cathode/anode

I was wondering the same thing. You'd think a positive E value would be desired because that would give a negative G value so the reaction would be spontaneous. Somebody please respond to this!

Galvanic Cell Potential Difference

Do you want the potential difference of you cell to be positive or negative? I assumed positive because that gives a negative Gibbs free energy value meaning that the process is spontaneous. How do you know which half-reaction to make the cathode and which to make the anode?

Can all elements exist in all states?

Given the right amount of energy and pressure, can all elements be converted into liquid, solid and gaseous states? For example, could gold exist as a gas?

Re: Max number in expanded octet

Xenon hexaflouride and sulfur hexaflouride both have six bonds, but I don't think I've seen a molecule with more than that.

Schrodinger Equation

Will we need to know the full version of Schrodinger's equation or just the simplified version from the course reader? Also, should I even try to understand the derivation of the equation?
