Dear Dr. Lavelle, Thank you for providing all kinds of resources to us and for dedicating all your time and energy to teaching students, many of whom you never even formally met. I didn't realize how much of a personal sacrifice you had to make in order to remain our professor, and I am so glad that...

We use Z and E when we're working with alkenes that need to be categorized as either cis or trans. Particularly when none of the 4 groups attached to the 2 carbons match. For example, on page 103 of the course reader, Z-1-Bromo-2-Chloropropene is named so due to the fact that none of the groups atta...

Katrina_Galian 1J

I don't think it does.

Katrina_Galian 1J

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

Katrina_Galian 1J

Why do chemistry professors like to teach about ammonia? Because it's basic material.

Katrina_Galian 1J

Yep!

Thank you, Dr. Lavelle, for giving us an extra credit opportunity.

Katrina_Galian 1J

Yes, it does.

You are a photon quanta to my valence electron. You excite me to a higher energy level.

Maybe by the end of this week. But chances are that they will input quiz grades when they put in the midterm grades too.

Katrina_Galian 1J

It can be both, but C is the standard unit. It's on page 18 of the course reader :)

Dr. Lavelle hasn't mentioned anything about posting modules for us yet. I hope he does though, as they're very informative and helpful.

If a king farts, is it a noble gas?

Got mole problems? Call Avogadro at 602-1023.

What do you call a tooth in a glass of water? A one molar solution.

Katrina_Galian 1J

Do you have 11 protons? Because you're sodium fine.

Are you a charged atom cuz I've got my ion on you.

Chem students do it on the table periodically XD

Katrina_Galian 1J

This sounds good, I'd like to join too!

Katrina_Galian 1J

Yes, it says on the class website that molecular orbital theory will be covered on the quiz.

Katrina_Galian 1J

Yes, you're right. When you draw the Lewis structure, the aluminum is the center atom and accepts electrons from the chloride, which is why it is a Lewis acid.

Katrina_Galian 1J

Haha down

Katrina_Galian 1J

I was wondering the same thing, but I think the safe thing to do is to just calculate the formal charge to check your work.

Katrina_Galian 1J

Wait, wouldn't the final energy level be 3? Since initial n is 1 because of the Lyman series.

Katrina_Galian 1J

For this question, I used a variation of the Rydberg equation found in the textbook on page 7. It accounts for the initial and final energy levels (n). Since the question is dealing with the ultraviolet spectrum, we know that it's going to be the Lyman series, which means that the initial n will be ...
