Re: Bonds

Yep, the axial is always up or down and the equatorial is always 109.5 degrees from the axial bond. In the chair conformation, the top of the chair has an axial up bond and equatorial down, and then from there it alternates axial down and up for all six carbons.

Re: 2014 Midterm Question 3

How would you know the reduction potential for these? Would they be given? Or is there another way to know?

Transition Steps

I am a little confused on the rules of transition steps.
In general, how do you know where to connect each of the atoms in the reaction?

Re: drawing line structures

Yes there are sometimes geometric isomers of the same molecule, depending on what you are given.
No it does not matter if you start with an up diagonal or down diagonal.

Re: Homework question 4.30

I was told that the answer is no because most organic reactions that have an activation energy under 80 kJ/mol will occur at room temperature, but I don't know if we are just supposed to know that or if there is a way to solve this problem.

Re: Spontaneity

w is positive if work is done by the system, and negative if work is done on the system.

w>0 work done by the system
w<0 work done on the system

Re: Homework Help 8.9

Yes it has to do with the units. There is a list of four equivalent gas constants on the back of the periodic table, use the one with the proper units, in the case of 8.9 I believe that it is 8.206x10^(-2) L.atm/K/mol

Adiabatic System

In homework question 8.15, it says the in an adiabatic system q<0 is never true. Why is this?

You use the molecular orbital diagram and find the bond order for each.

I asked the guy sitting next to me if he had any Sodium Hypobromite…
He said NaBrO
