Re: Specific Bond Angles

I believe we should also understand dihedral angles and how to draw and label them staggered vs. eclipsed.

Re: Special cases with nomenclature [ENDORSED]

Another nomenclature question: On March 8th's lecture, Dr. Lavelle explained that a double bond receives the lowest number when naming and alkene for example, just as a functional group would. But what if a molecule has a double bond and a functional group? Which do we assign priority for the lowest...

Re: Ether Naming

Does the ether group always appear first when naming? For instance on page 100 of the course reader, for 1-ethoxy-3-methylpentane, would we put the methyl first if it instead happened to be butyl, making it alphabetically first?

Bruincast for February 13, 2017 [ENDORSED]

Are the last couple minutes of February 13's lecture not working on Bruincast for anyone else?

Re: products in rate law equation

And if we do end up needing those more specific formulas/values, I believe they will be provided, similarly to constants or tabular data.

Re: Review from 14a

K is usually given. Q, as in the reaction quotient, is given by the concentration of products over the concentration of reactants. If K=Q, the reaction is at equilibrium.

Re: Reduction Potentials

You make negative the value that corresponds to the half reaction that must be reversed in order to balance the desired equation..

Re: Entropy

Not always, but an increase in entropy is favorable for systems as opposed to a decrease in entropy.

Re: Sytem Behavior

I believe this is because deltaU, internal energy, doesn't cover the possibility of having a spontaneous process in system without an energy change. For example, energy in a system can remain the same but the volume of a system can increase, expanding the gas due to entropy and not due to any change...

Re: Ch. 8 Question 8.61 (Hess's Law)

We would use this approach assuming we were not given something like the Appendix data regarding enthalpies of formation right? Or are these two different concepts.

Re: Calculating q using a heating curve

Not that I know of, since each Q yields a potentially different value depending on the state and temperature of the object you're studying. Hopefully I'm wrong though and there's a quicker way?
