Chair Flipping
Hi! Can anyone explain how to carry out chair flipping? Like how do you re-number it and know where to put the functional groups on the newly flipped structure?

I think we are expected to know all four: anti, gauche, slightly eclipsed, and fully eclipsed.

Re: Final Exam Details and Review Sessions Winter 2017
Will the final emphasize more on current topics? Or will the questions be evenly distributed across all topics?

For the quiz, are we expected to express the compounds through the skeletal/line-angle formula or through lewis dot structure?

Re: Quiz 3 Winter 2017
Hi! Why is the answer for number 4, 4-butyl-1,2-dimethylcyclohexane and not 1,2-dimethyl,4-butylcyclohexane?
When naming a compound, do the lower numbers do first?

Re: Reversible vs. Irreversible [ENDORSED]
Okay thanks! That helps clarify things, but I was also wondering how each condition affects one's calculations for a certain reaction? And how it affects the temperature, pressure, etc

Hi! We went over enthalpy in lecture today and Professor Lavelle drew out a diagram as an example, but I am still confused on why enthalpy is a state function. Any help is appreciated!
