In the organic textbook, it names alcohols, for example, 2-propanol, but on the practice finals it names them more like propan-2-ol
Is one method preferred for the final or does it not matter?

Re: Cis Trans
Just to add on, you also want to look at if the two priority groups on the cyclohexane are axial or equatorial. If they are both axial up or both axial down /both equatorial up or both equatorial down, it will be Cis. If one priority group is axial up and the other is axial down then it is considere...

Re: Chair vs. Boat
Chair conformation is more stable than the boat confirmation. In the boat confirmation the hydrogens are bumping into each other (flagpole interactions), therefore causing steric strain. Chair conformation has no steric strain because no atoms are bumping into each other, the H on the adjacent C is ...

2015 Final Q9A
Can someone explain how to name the second structure in this question?
It's 1-(3-chlorocycloheptyl)-2-methylpropan-2-ol
I'm confused why it was named in that order. Where did they start numbering? What does the 1 represent in the beginning? & which carbon chain was seen as the longest/shortest?

remember we want to start numbering wherever we could get the lowest number, so in 4-butyl-1,2-dimethylcyclohexane (4+2+1 gives us 7) whereas 1,butyl-3,4-butylcyclohexane (4+3+1 gives us 8)

Re: Midterm 2013 Question 3A
Hi, I am still uncertain to how they got 2259 J/g for delta_h vaporization of water when the formula sheet shows its 40.7 kgxmol-1.
So exactly was that calculated ?
Thanks in advance !

Re: Homework Problem 14.9
Hi, so I'm pretty sure to get 2 moles of electrons you split them into half reactions first. So you initially have 2Ce4+ = 2Ce3+ On the left side you have a charge of 8+ (2 x 4+) and on the right you have a charge of 6+, so you need 2 more electrons to balance it out. In the second half rxn you init...

14.5 Basic Solutions
Hi, im not sure if this is an obvious answer, but in comparing 14.5 (a) and 14.5 (c) I am a bit confused as to why some H2O's cancel out from both sides and others don't. For example in part (a) you have the FINAL balanced reaction 6OH- + 3H2O + Br- = BrO3- + 6H2O + 6e- and you're left with H2O on b...

8.99 Heat Capacity
Hi I am a bit confused as to why in the solutions manual, the heat capacity used in this problem is negative (-4.184).
The problem says to assume the molar heat capacity is the same as water, so initially I thought that would be positive?

Intensive vs. Extensive [ENDORSED]
Hi, this probably simple, but I am a bit confused on difference between an extensive and intensive property?
I know heat capacity is an extensive property because the heat required depends on the amount of substance, but what makes an intensive property?

Hi, so in the course reader it says Quiz 1 will start January 31 in your discussion section. So your quiz will be within that week.
