Chair conformations Cis and Trans
I was wondering whether Cis was with both being the same orientation or the same direction. Can it still be Cis with a an equatorial up and equatorial down or would that be considered Trans? Thanks!

Equatorial and Axial confusion
I am still confused on equatorial and axial. Can we put the bigger molecule in either axial or equatorial and would it make a difference? Thanks in advance!

Benzene
Should we expect Benzenes to be part of Quiz 3? If so, then can I also label them as Cyclobenzene or is that already implied?

Cyclohexene and double bonds
When I came across a cyclohexene with a methyl group and I saw that it had a double bond. Does it matter where we place the double bond and methyl group in the ring and will it change the cyclohexene into another compound?

Is there such a thing as a Third Order Reaction?
I was looking some videos up on youtube about zero, first, and second order reactions and they briefly mention a third and fourth order reaction. Is it possible that we will ever use this on our quiz and final?

H in redox
I was searching online for any special rules we'd have to follow in order to get the oxidation numbers for each element and I found some websites stating that Hydrogen is both +1 and -1 for metals and nonmetals. One in particular said that Hydrogen is -1 when with non-metals and + with metals and th...

Oxygen Ion Charge
Looking at Redox rules that some of the elements have and I saw that Oxygen has a -1 charge rather than a -2. How can that be? Is there certain compounds that will cause oxygen to have a -1 charge? Does oxygen impact the charge on other elements as well? Thanks!

Ex 9.7 pg 331. Boltzmanns Formula
I'm still confused on the whole concept of W. and how in the first step of Example 9.7 they got W = 2^4? What exactly does this represent? I see that W is the number of ways atom molecules could be arranged, but will W always be given? We would have to find that out on our own if given enough inform...

Bond Enthalpies of Diatomic Molecules
In Ch.8 in Table 8.6 are those the only Molecules that we could use? Is there more? I've been sort of confused and would like some clarification. Thanks!

Expansion work
Does anybody know whether or not we will be using these equations heavily? w = PexA x d or w = -Pex V ? If so would someone care to explain on how to utilize these equations? Thanks!
