An anti-Newman formation is when the two largest functional groups of each carbon are 180 degrees from each other. A gauche formation is when the two largest functional groups of each carbon are 60 degrees from each other.
Both these formation are variations of staggered.

Ether Naming
I'm still somewhat confused on the ether naming. Is it possible if someone can give and complete an example?

Showing Electron Arrangement
I noticed in the course reader on page 83 that there is a difference in the arrows used to show the movement of one electron and two electrons.
Is this important? On the quiz will we need to strictly use a one sided arrow to show only one electron moving?

Re: First order, second order reactions [ENDORSED]
We are tested on everything up to page 73 in the course reader. This page ends with "Pre-equilibrium approach".

When to add H+ in cell diagram?
On page 144 in the course reader, part C says to write the cell diagram and it includes H+ in the diagram.
How do we know when to use H+ in the diagram?

Re: How do I find oxidation number?
Hi I had a similar question. My PLF gave me an answer with specific steps. 1. The oxidation state of a lone element or free state is zero. For example if you see a long element such as Cu, Zn, Ag. The O.S. will be zero. There are 8 diatomic elements to remember who's O.S. is zero as well: H2, O2, N2...

Energy Extensive or Intensive?
I was looking at an old quiz and it asked if energy was extensive or intensive.

Gibbs Free Energy Problem on pg 39
On page 39 in the course reader, there is an example problem Lavelle went over. It says that deltaG is equal to zero.
Why does the delta G equal to zero?

Re: Ch 8. Q.1 [ENDORSED]
Hi, I'm curious as to why d) gasoline burning in an automobile engine is an open system rather than closed? Since the engine is within the car, right? An open system is defined as a system where matter and energy can transfer with the surrounds. SO specifically with this question, because you are a...

Re: Bond Enthalpies
In using this method, when a bond is formed do we write it as negative energy, and when a bond is broken, we write it as positive energy to add them up? When a bond a formed, energy is released so that will be positive energy. When the bond is broken, energy is used, making it negative. To find the...
