Naming Organic Compounds - Branched Chain Alkanes

[@daicyyang6815]

I normally don't comment on videos, but truly this video was a lifesaver. You explained this in 10 minutes that someone else would have taken an entire 2 hour long class to teach. Thank you so much I finally understand this.

[@Leah4sci]

I'm so glad to hear this was helpful to you! You're very welcome.

[@kittylola643]

I have been sort of struggling with Organic Chemistry. This really simplified things and allowed me to finish my homework in a breeze. I will be watching through out Organic Chem I. :)

[@kittylola643]

Currently, we are going over R and S, meso, chiral, and achiral, sterochemistry, enamors, diisomers, fisher's models, and that's all I can think of off the top of my head. (hopefully the spelling is close enough)

[@Leah4sci]

So happy I could help!

[@studygroupprepusmle]

I am so impressed with your videos, I needed to quickly review my organic chemistry and had forgotten everything. After watching 2-3 videos of yours, I practiced some questions in my course and immediately got the right answer, you saved me days of reviewing and studying lol.. big thank you

This is the third time reviewing this video and it really helps drill into me the importance of finding my mind's shortcuts to help me really understand !! We need more orgo prof's like you! It's sad, though, because there is only 55 minutes for each class..

waw, i wasted 2 whole weeks in school learning about organic chemistry, which i didnt even pay attention in....all i could have done was watch this video. p.s i have my 10th board exams in a week so THANK YOU !

[@FixitFox]

So glad I found these videos, thank you for these! How do we know whether there's a double/triple bond or not without drawing out the Lewis structure?

[@Leah4sci]

Glad they're helping. If given just a molecular formula, look at the # of H atoms. If there are too few, you have a pi bond For example: CHCCH3 has a triple bond where CH2CHCH3 has a double bond

at 7:25 why did you highlight upward instead of continuing to the right? Continuing to the right would have also given you a 7-carbon chain?

It would be the same end result no matter which one was chosen.

[@DelaciaJohnson]

I confused, on the first tricky question, if the substituent is on the third carbon why isn’t it prop instead of ethyl

[@Leah4sci]

The substituent prefix comes from the number of carbons in the substituent itself rather than where it appears on the chain. Therefor, a 2 carbon substituent will be ethyl regardless of where it shows up

[@pragatiix09]

It helped me a lot😊

[@Leah4sci]

Awesome! Glad I could help

[@angeloualbano529]

I kinda got confused on 6:09. why not choose the (1,2) on the right side? it also gives 6 carbon chain just the same as the left side? thank you :)

[@angeloualbano529]

thank you!

[@stem5118]

at 4:05 how do you know the parent chain is the straight across and not the straight across including the bottom branch? do parent chains have to be straight across?

[@Leah4sci]

This is explained in the video. You can use both options so long as you choose the longer path. If same length either one is correct.

[@elianadiaz7435]

Hi Ms. Fisch, I thought you read parent chains from right to left instead of left to right in your butane example with the two carbons on the 2nd carbon?

[@elianadiaz7435]

Just kidding. I figured it out with the next example!
