Yes, axial are the ones that are vertical while equitorial (think equator) are the horizontal-ish ones

My TA said to either write out electrophilic addition or Sn2, it doesn't matter as long as you get it right!

In lecture, Lavelle went over how to draw them. Here are some key things he went over: 1. They are always drawn in the perspective of the carbon chain 2. The carbon in the back is drawn like a circle, with its respective hydrogens coming out of the circle. 3. Make sure you specify whether it is a st...

"Hi! Nice to meet you! What's your name?"
"I'm dead."
"Am I dead, too??"
"No! My name is DiEthyl Azo Dicarboxylate! DEAD for short."

Organic chemistry is difficult... those who study it have alkynes of trouble

With Valentine's Day coming up...

Are you made of uranium and iodine? Because all I can see is U and I!

Make sure to also flip or "reverse" the equation when needed! If you're finding E, remember that when you multiply the equation to get the same number of moles, you DO NOT multiply E like we did in Hess's law. We just switch the sign if we reverse the equation.

“What is the difference between thermodynamics and a stick?

“A stick has two ends and no beginning. Thermodynamics has two ‘beginnings’ (the first and second law) and no end.”

So Lavelle just posted a bunch of information regarding derivations under the announcements tab! Go check it out!

paulapedrani

My best guess is that we will have to know all of the equations given to us that are not on the formula sheet, and the best way to know those is to derive them :/

Why do white bears dissolve in water?
Because they're polar

Hi all! I am currently enrolled in discussion 2L (Fridays from 2-2:50) and am looking to switch into 2I (Thursdays from 4-4:50) let me know if you're able to switch!!

paulapedrani

Hope everyone has a good (B)Boron (Re)Rhenium (A) (K) Potassium!!!

So finals week is coming up... make sure you all get your CoFe2 in the morning!

paulapedrani

and make sure you know that nm is x 10^-9!

paulapedrani

you just answered your own question lol
if k is in between those values, then neither the reactants or the products are favored. if it is less, then reactants are favored, and if it is greater, then the products are favored

paulapedrani

We never did this in lecture, but yes, you divide by Avogadro's number. For that specific question, once you got the energy, you have find the wavelength and then determine if it was in the range of visible light. (visible light being from 400-700 nm)

paulapedrani

I'm pretty sure that if you know the wavelength for visible light, which is 400-700 nanometers, then you should be fine. (Red being around 700 nm, violet being around 400.)

The best Lewis structure is one where the FC is zero. Ideally, you want the FC to be between one and negative one. The overall charge is the same as each one's FC combined. So if it's CN-, you would want the addition of all the formal charges to be negative one

3 but I have to go to urgent care right now (i'm super sick) but I'll meet up with you guys as soon as I get back! I shouldn't be back any later than 3:30

paulapedrani

: There was a raid and the theme was "James Bond and Legally Blonde"... guess who the science majors are lol

paulapedrani

It's official everyone mark your calendars....This Sunday, 10/23, study sesh in the De Neve Evergreen floor three lounge at 3! :)))))

I'm not quite sure what you mean, but if you look at the periodic table Lavelle provided, you can see the patterns of electron configuration there. There's usually a pattern, except when it gets to chromium, instead of following the trend and being [AR] 3d^4 4s^2, it became [AR]3d^5 4s^1. The electr...

My TA said we could use either one, but since you can get partial credit in the quizzes, he recommended we use the one Lavelle was talking about so that there are less chances of making a mistake and more chances of getting partial credit if we do!

paulapedrani

I'm in Evergreen! Do you guys all want to get together maybe on Sunday to review everything from week one?

paulapedrani

Does anyone in De Neve want to make a study group? It's only been two days and I already feel behind.
