Leah you're an ANGEL. I recommend you to everyone in my class. You're so thorough and concise and your passion comes through in every video. Please keep it up, you help us struggling students so much.
Hello Professor, I still don't understand how cis/trans and E/Z differ. It seems to me that both cis and Z have the same side similarities, while trans and E have opposite side similarities.
They do often overlap. Cis and Trans is typically used for pi bonds in a chain with nothing else on the pi bound carbons, while E and Z are typically used when there is a lot more going on, for example having substituents on the pi bond in addition to alkyl groups. I demonstrate many examples in this tutorial leah4sci.com/cistrans
So would it jump in with the R and S in numerical order? (2R,4Z,6S)? I like less letters (E/Z). I also prefer R...but-2-ene as opposed to R...2-butene. And I'm lazy so I always draw fully aromatic with a circle.
@@trixinreno419 it really depends on how your professor wants the answer written out as the 2-butene and but-2-ene are both correct. I prefer the first as it flows better. And yes to aromatic circles, OMG the drawing required in an aromatic mechanism... 🤦

Awww, thanks so much, that means a lot! I'm happy to hear you're finding the videos helpful.
Hi Leah, i passed my Ochem 2 ACS today, just want to say thanks for the help!
Oh wow, thank you so much for hopping in here to let me know. the ACS is no joke, congratulations and you are so very welcome! What's next for you?
How was it?! I have it today and I am panicking!
I have a full guide on how to prepare for the ACS
take a look here and let me know if it helps tleah4sci.com/acs
I just saw this, oh no to panicking! How did it turn out?
For the 7 membered chain in 50:00-57:30 , how come there is no mention of E/Z for the double bond? Is it because it's trisubstituted?
Oh you're right! You can definitely use E/Z for that, I simply didn't think to include it
do you have anything for NMR and IR spectroscopy?
Have you seen this on my website?

Thank you! You saved me !!!❤❤
You are so very welcome! Wishing you all the best on your final exam
Hi prof Leah if the charge is a negative one is that counted as a hybrid orbital
Yes, negative electrons exist in the hybridized orbital unless they are participating in resonance
can I get the resonance quiz? your videos have helped me so much preparing for exams and now the ACS orgo 1 final
Best of luck on your upcoming exam and ACS final. See below for the resonance quiz and my ACS guide

They do overlap, it's simply a question of what else is going on in the molecule
57:04 4-cis? Or 4Z?
Cis although Z also work

Hi I have my organic finals tomorrow can you link me some alkenes and alkynes reaction, different mechancis
Just saw this, but you can find all of my resources easily with my syllabus guide:

Thanks alot!!!!!
You're very welcome! Hope it helped you prepare for your final exam
Hii leah!!!!
Hi
DAMN I MISSED IT
But did you? ;)
I love that RUclips allows me to immediately post the recording, I assume you're all caught up? See you tonight for part 2?
I thought oxygen was more electronegative than bromine 1:16:55
Yes, oxygen is 3.44 and Br only 2.96
thanks
You're welcome, good luck on your finals!
