Midterm 2 content

Postby Meghan Krushena 2E » Sun Nov 15, 2020 10:17 pm

Are there any equations we need to know for midterm 2? Like I understand all the rules and trends we need to know, but I wasn't sure if we need to know Shrodingers Equation or any other equations...like are there going to be calculation problems?

I feel like this unit is more about structures... but I could be wrong.

I believe any equations that we need will be provided to us. The exam is probably more focused on if we know how to use an equation than if we can memorize it.

I think the only equation we probably need to know is the formal charge equation to help us with Lewis structures. But besides that, I don't think there will be any other calculation problems on this midterm.

Based on the sapling homework it doesn’t seem like we’ve been using an memorizing equations lately. I think it’ll mostly if not all be Lewis structures and understanding of different bonds/forces.

Hi!
Based on the homework that was due week 6, it seems like this midterm's content is not as focused on calculations but rather concepts and drawing Lewis structures. I would refer to the outline posted on Lavelle's website to know exactly what we should study, though. Lavelle also has office hours on Monday and Wednesday, where I'm sure he could clarify what exactly we need to know. Best of luck preparing!

I believe most of the content will be based in Lewis structures

Based on sapling, the midterm this time seems to focus more on the structure of molecules. The only real equation we might need to know is the formal charge equation, at least to my knowledge.

I think the best prep for this midterm is definitely all of the lecture notes and textbook problems because it is less math and more practicing structures to be prepared for what we may see.

Hi what time are his office hours again on monday ?

I think this midterm will be more focused on bonding and Lewis structures. So just be ready to calculate formal charge.

Hopefully, since more questions hopefully we have enough time.

Has Dr. Lavelle told us how many questions are going to be on midterm 2?

It's only the last 8 bullet points of outline 2 and outline 3, so I would think that we don't have to remember that content until we get to the final!

I think the content is more conceptual. The only equation I can think of using is the one for formal charge

The only equation that I think we will need to know is Formal Charge:


Formal Charge of Atom = V - L - B/2
- V - Valence Electrons of Atom - found using the periodic table of elements
- L # of Lone Electrons on Atom - these are the lone individual electrons
- B/2 # bonded electrons with Atom/2 - each line represents 2 electrons bonded and formula calls for you to divide the number of electrons by 2. a simple way to do this is count the number of lines the atom has coming off of it


Also you will need to know how the dipole moments formula works (mu= delta * d)
- mu = bond dipole
- delta = charge
- d = distance between partial charges (bond length)
An increase in bond length increases the dipole moments.

I agree with everyone. Midterm 2 will cover topics after midterm 1. So, equations such as Schrodinger's, Heisenberg's, etc.. are most likely not on the exam. I think Midterm 2 will focus on Quantum numbers and onwards (Electron Configuration, Lewis Structures, etc.)

This unit is definitely more conceptually-focused than the previous one. I don't think there should be any major calculations since we're expected to know most of the introduced equations conceptually.

I think just formal charge and maybe the equation for potential energy in london dispersion forces which involves the polarizability of the two molecules divided by the distance between them^6.

As many have already stated, lewis structures is a key focus for this section. It would be helpful to do the sapling textbook problems to practice making these. I believe this midterm stops content-wise at hydrogen bonding.

Shrodinger equation is from the first midterm. It would not be on the second.
