Hello,
Just out of currosity, are Newman projections only used for 2 carbon structures? What would happen if you wanted to draw 3 or 4 carbon structures?
Thank you!

Naming a Alkene with a Functional Group
I just had a conceptual question: if a double bond is considered a functional group, it gets priority in naming. But what happens when there is another functional group, let's say an alcohol, attacked to the alkene. Which functional group gets priority in naming?
Thanks!
Thanks!

Molecule Structure in Reaction Mechanisms
When drawing out reaction mechanisms, I still get confused as to when to add partial positive and negative symbols to the atoms in molecules and when to label certain things. Is there a certain convention that exists?
Thanks!
Thanks!

Orders for Reactions
When reviewing the notes, it seems that the order of reactions in some cases (like elementary steps for overall reactions) can be found just with the coefficients. However, in other cases (I do not know which), you cannot consider the coefficients to be the order for the reactants. In which scenario...

Disregarding Products and Focusing on Reactants
I am still a little confused on why exactly you can disregard the products that are formed and just focus on the reactants in order to get the rate. It is just a little conceptually difficult to wrap my mind around, so maybe someone could explain!
Thanks for the help!

Winter Midterm 2013 Q2C
In this problem, my course reader had multiple answers printed and I don't know which is correct.
Is the answer supposed to me more or less ice?
Thanks!!

Making Half Reactions and Including Cell Potential
When I was doing some of the homework and going over my answers using the solution manual, I noticed that the solution manual always included the standard cell potentials of the half reactions, even if the question asked you just to create half reactions and make a balanced equation. Is it standard ...

Concept of Entropy and Enthalpy is Constant for Changing Temperatures
In the derivation of the Van't Hoff Equation used to calculate K at a different T if change in enthalpy is unknown, why is it appropriate to assume that the change in entropy and the change in enthalpy are constant when there is a temperature change? if the temperature change is large, won't there b...

Gibbs Free Energy of Formation
If, according to what Professor Lavelle stated, gibbs free energy can't be measured directly, how is it that gibbs free energies of formation are able to be calculated? How is that done?
Thanks!
Thanks!

Reaction Enthalpies: When kJ and when kJ/mol?
In several of the chapter 8 homework problems we have had to do, sometimes the reaction enthalpy will need to be in kJ/mol, often in order to continue the problem and result in just kJ, but sometimes it does not. I am confused by when kJ or kJ/mol is used with standard reaction enthalpies because it...

Re: Cha. 8 HW Problem #57
I think it IS supposed to be entalphy of combustion! on page 296 towards the bottom in Example 8.11, it says entalphy of combustion and then writes "delta H subscript c." Either way, the numbers for the entalphy are given to you, so what EXACTLY the c means does not matter in this case! Ho...
