Boat conformation
Hi guys, I was wondering if a boat conformation also has axial and equatorial bonds? Thanks in advance!

Re: Prefix naming
Just to provide an example, the following is a name for an organic molecule: 4-( tert -butyl)-6-isopropyl-1-methyl-2-propylcycloheptane. As you can see, tert is not taken into consideration when alphabetizing. The same thing applies to the prefixes di and tri. However, iso and neo are taken into con...

Re: Naming Organic Compounds
Yes, I believe it does, but it is much easier to just look at the smaller number. In this case, it will be 2, so the first one (4-ethyl-2, 2-dimethyl-hexane) is the correct way of naming.

Catalyst question
Hi, from what I understand catalysts are part of the rate law. Is this correct? Thank you!

Comparing molar entropies of different molecules
Hi,
What takes the priority when comparing molar entropy of substances? Do we look at the state first and then consider degeneracy and then molecular weight? I know that similar questions have been asked, but I've found different answers about this. Thank you in advance!

Re: Cell Diagram
Hey, When you are writing a cell diagram, everything on the right of the double vertical lines is part of the cathode and everything on the left is the anode. And yes, you are right, in the example in the course reader on page 48, Fe^3+ and Fe^2+ are separated by a comma because they are both part o...

Quiz 1 Preparation Help
Hi guys, I was going through quiz 1 preparation and I needed some help. I'll post the question here for reference: "A sample of 1 mol of gas initially at 1atm and 298K is heated at constant pressure to 350K, then the gas is compressed isothermally to its initial volume and finally it is cooled ...

Clarification regarding reversible, isothermal expansion [ENDORSED]
I am still unsure about the difference between reversible, isothermal expansion and irreversible expansion. I understand that we can use the following formula to calculate the work done by a system against constant pressure: w=-P(deltav). For a reversible, isothermal expansion, the work is calculate...

Re: Standard reaction of enthalpy
Great question. Standard reaction enthalpy is the reaction enthalpy when all the reactants and products are in their standard state at 1atm. This is very significant because most reactions are given in their standard state. As discussed on Wednesday's lecture, we can calculate the standard reaction ...
