Nomenclature Practice (Final)

I found this website that lets you practice organic nomenclature. You can choose to draw structures from formulas or determine names from structures, modify which functional groups you'd like to practice, or simply generate a random test. It's truly the most comprehensive site I've used so far, and ...

Exergonic vs Endergonic Reactions [ENDORSED]

I know it seems like a very simple thing to memorize, but are we expected to know the difference between these two types of reactions (with respect to the values of K and the Standard Gibbs Free Energy of Reaction)?

Reaction Mechanisms

I noticed that there are quite a few reaction mechanisms mentioned throughout the o-chem textbook. Which ones are we responsible for understanding? All of them I presume?

Extra Practice for Determining Rate Laws using Initial Rates

I found this website while studying for the second quiz. It provides great examples with detailed explanations of the solutions. Thought it was a pretty neat tool for those who are still confused about rate laws, or those who simply want to get some extra practice in before the quiz. http://www.chem...

A man was stopped for having sodium chloride and a nine-volt in his car.
He was booked for a salt and battery.

Re: Chem 14B Course reader

Thank you for the responses. I bought the course reader, and I'm already noticing a difference in understanding of the material. Thank you both for responding!

Chem 14B Course reader

I took 14A with Dr.Lavelle last quarter, and I didn't do as well as I wanted to. I thought it might be because I switched into the class late, or because I had trouble adjusting to the classes here at UCLA. In any case, I did spend an enormous amount of time studying, but it felt like the exams were...

Re: CH 8 Which HW Problems to do first?

Will there be a list of recommended readings for each chapter? Like a certain chapter or section of the textbook to read before each lecture? Without knowing we would begin the course with thermochemistry, I spent the week before instruction began studying Ch.8, beginning with thermodynamics. Altho...

Dipole moment

When we're looking to investigate the dipole moment of a compound such as water, it would make sense to find that there are polar covalent bonds involved. As a result of the partial charges distributed among the molecule, it would seem water has distinguishing characteristics. Although it's not dire...
