AP Chem - Unit 2 Review - Compound Structure and Properties

[@solr8948]

these videos are short and concise, totally underrated

[@JeremyKrug]

Thanks! I hope they're of use to you with the upcoming AP reviews in your class.

[@suhasalloum3819]

this is me watching the whole series 2hrs before my exam. all i can say is you're an absolute angel for doing this!! extremely helpful and informative!

[@JeremyKrug]

Thanks for watching, and even more thanks for your kind comments!

[@vanessa_tan06]

Yo this is definitely helping with my last min review (aka intense cramming 💀) for the AP exam- thanks very much!

[@JeremyKrug]

It's cram weekend. Don't forget to get some good rest before that exam!

[@Mitblade]

fr actually goated. ik there are like 1000s of these types of videos, but none as simple and easy as this. It covers everything u need to know and makes it simple to understand.

[@JeremyKrug]

Thanks for the kind words. I'm glad you like, and I hope you find my other videos just as helpful!

[@krishnannarayanan8819]

Thank you Mr. Tom Cruise, now I am more ready for my AP Chem exam! Seriously though, thank you so much! These videos help so much!

[@JeremyKrug]

Wow, I've never been compared to Tom Cruise before :-) Glad my videos are of help!

[@fatimabah5663]

I was also so scared but these videos r rlly helping ahah

[@abel6298]

So information packed, first time I watched it I learned a lot but didn't do too well on my homework because I did not pay that much attention during class. After reviewing what I missed, the second watch around I realized just how much I missed from the explanation on this video. Thank you so much!

[@JeremyKrug]

So glad you liked! You're right, there is so much in each video that it can be hard to take it all in the first time around. Thanks for watching!

[@not_luciiaa7663]

these videos are the only ones I can watch that keep my Adhd in check, thank you Mr. Krug!

[@JeremyKrug]

I'm glad my videos work for you. Sometimes a quick refresher is all you need. Good luck on the exam!

[@graceb07]

Hi! My AP chem final is tomrrow and I'm reviewing the 4 units we have done thus far and these videos are helping a lot. Thank you!

[@JeremyKrug]

Thanks so much for watching. You're going to do great on your final!

[@zhixinliu2202]

the greatest chemistry teacher in the world!!!this video saves my life

[@JeremyKrug]

Thanks for the compliment. I'm glad this video helped you out!

[@swoosh6801]

I have a midterm tomorrow and these videos have helped me so much to review! Thank you so much for these videos

[@JeremyKrug]

So glad you find them helpful. Thanks for watching!

[@ghassanqattan9832]

How many times can we thank you for such great vids, helpful, and great quality ❤️🙏 you're the best, wish you actually all the best in the world. Thank you 😊

[@JeremyKrug]

Thanks so much for watching, and I really appreciate your kind words. I hope to keep making videos for a long time to come!

[@AbhiChintz.]

Thank you so much struggling in the class atm and I haven't taken Honors, so these videos are extremely helpful.

[@JeremyKrug]

Always glad to help. You've got this!

[@monireachkong4946]

Thank you sir for making such videos. They are very helpful.

[@JeremyKrug]

Thank you for watching! I hope you find them useful as you review.

[@duck-vt4co]

in 10:37 , are the unshared pairs for the central or the other atoms? Also your videos are the best out there!!!!

[@JeremyKrug]

The unshared pairs that we 'count' are the ones on the central atom only. Those are the ones that affect the actual shape. Great question!

[@HazmatGamer9842]

Perfect Review for my unit 2 test. Thank You.

[@JeremyKrug]

Glad it was helpful!

[@RLSTUD1OS]

Im taking the unit 2 test tmr and this is helping.

[@JeremyKrug]

Best wishes on your Unit 2 Test!

[@airoRBLX]

howd you do?

[@longblanket27]

Thank you so much for making this video! It is really helping me 👍

[@JeremyKrug]

I'm so glad it's helpful to you!

[@lucaswang391]

how do you count unshared pairs? also, whenever counting the hybridization, do you always just add 1 because the sigma value is always 1?

[@JeremyKrug]

Each pair of electrons touching the central atom that doesn't touch another atom counts as an unshared pair. For hybridization, the number of sigma bonds is the same as the number of other atoms the central atom is touching. So sigma bonds would most likely be a number between 2 and 6.

[@stellayu7998]

Great review videos, thanks!

[@JeremyKrug]

Thanks! Just 8 more days to go until the AP exam!

[@jordand7396]

if possible please explain how you got the added up numbers for the hybridization at topic 7 10:10

[@JeremyKrug]

Just count the number of atoms the central atom is attached to, then add the number of unshared electron pairs on that central atom.

[@borispasternak2356]

Question, at 4:21, isn't a sodium atom bigger than that of chlorine? Since in terms of trends, it is on the same row and leftwards, therefore should be bigger, or?

[@JeremyKrug]

Yes, but notice that these are ions, not uncharged atoms. Cations are generally smaller than the anions that they associate with. Great question!

[@borispasternak2356]

@@JeremyKrug I see, thank you so much for the swift reply!
