Hi everyone!
It's almost time for the second midterm, so I'll be making a Midterm review worksheet again. I mentioned that I might be able to host a Zoom to review the worksheet, but I decided because of Veteran's Day and the number of students who use the worksheets but don't come to the live session, that it would be a better use of my time to make a thorough answer key for y'all to check with.
I will be posting the worksheet and answer key tomorrow!

Re: Patrick's Week 7 Step-Up - MIDTERM 2 REVIEW
Copy pasted midterm info from my last midterm review:
QUICK DISCLAIMER this doesn't cover everything on your midterm, and I don't know what your midterm looks like! I made this worksheet to try and hit as many of the learning outcomes Dr. Lavelle set, but you should definitely keep studying with your other resources
Some other notes if you're cramming for the midterm right now:
1. Study effectively -- I recommend going back and doing all the textbook questions if you have the chance, but you shouldn't be doing textbook questions on the day of the midterm. When next Monday comes around, I recommend reviewing the LEARNING OUTCOMES:
- https://lavelle.chem.ucla.edu/wp-conten ... _Bonds.pdf
Find a friend (or just talk out loud), create a google doc, and write down literally EVERYTHING you can think of for each bullet (types of potential questions, any definitions, or any important info/concepts relating to that). If you can do that from your memory, that means you understand that learning objective. This might be a better use of your time on the day of the midterm, because you should be reviewing and not learning (best case scenario).
2. Know your resources! There are a TON of UA sessions this week and previous worksheets! If you found any of the questions on my worksheet hard, figure out the topic, and go to one of my (or any UA's) previous worksheets and focus up on that.
3. Make sure you understand and can explain any trends/equations -- It might seem simple, but this material is highly theoretical, so you don't wanna trip up because you assumed a trend or equation seemed straightforward enough.
If you have any questions, make sure to use Chemistry Community, reach out to any of the CHEM 14A team, or drop your worksheet-relavent questions below.
YOU GOT THIS :)

Re: Patrick's Week 7 Step-Up - MIDTERM 2 REVIEW
Hi,
For question 10, I think the atoms in the question are not aligning with the ones ranked on the answer sheet. Also, for question 11, isn't hydrogen bonding (-20 kj/mol) stronger than ion-dipole (-15 kj/mol)?

Hey Angel (and anyone else reading this)
Sorry about question 10, I was writing multiple versions for that concept and mixed those up. While the answer is for a different set of atoms, the concept remains the same, and I guess you can make two questions out of that then.
For Question 11, you are 100% correct! To clarify, the answer to question 11 should be A> E > B > C > D > F. The answer you see on the answer key was what we were told last year if I remember correctly, but yes, hydrogen bonding is stronger than ion-dipole.
Good catch!

Re: Patrick's Week 7 Step-Up - MIDTERM 2 REVIEW
I have a question for Q4
For how many hydrogen bonds can be made, you highlighted the S-H portion, wouldn't that not be possible since H is not bonded to N/O/F?

Totally my mistake, you're correct that only N/O/F should be able to form hydrogen bonds. Sorry about that should have checked my work better!
