I think confusion with the last example comes from not being sure how to deal with a ring. This would be one way to go about it: 1) Start at a particular carbon on a ring and follow a path (i.e. clockwise) all the way around that returns you to your starting point. 2) Begin at the same carbon and follow a path all the way around in the opposite direction (i.e. counterclockwise). 3) If the paths in both directions were the same, your starting carbon would NOT be a chiral center because the ring itself would be symmetrical (so therefore there aren't 4 different groups attached). If the paths differed at some point (for example, say that the ring has an OH group and you encounter that group sooner as you move clockwise around the ring than if you moved counterclockwise) then your starting carbon would be a chiral center. It's hard to explain it without a demonstration, but hopefully that helps anyone that was also confused!

My first year in college here. I could not afford the book i needed for this kind of stuff since it was criminally expensive. The book was would have contained a code which would grant me acces to an online portal where aditional information and practice exersices are located. I did not have any of this. Your videos are the sole reason im passing the year. Just wanted to let you know how thankfull i am.

Oh my God I've been trying to figure it out for hours... 4 different groups... DIFFERENT.... the book/cengage/professor/video no one put an emphasis on it!

i dont get how when i teach somebody shit ill explain every detail you need to know but when a professional professor teaches they dont explain important crucial shit to solve problems. Like i literally had no idea there was an invisible hydrogen atom which is why i kept thinking how is there four groups when i only see three and are given three. its not that hard for a teacher to mention something like that but they still seem to fail to do it. this dude is honestly my main professor this semester its sad

OMFG I finally understand! Thank you! I thought it had to be different ATOMS but it’s more like different GROUPS! Thank you 🙏🏼

You are saving lives your way. My goodness! Thank you

I've been learning so so much with your videos! It really helps out more than many books! thanks loads

Thanks a lot!🌸However,the last example is a big challenge😩😭😭

Seriously the best explantion ever heard about chirality and chiral molecules with such good explanation with examples

👌🏿sweet. My organic chemistry teacher teaches @ 60mph. Here I can learn everything with peace!!!

Explain last example properly

I'm loving this content! I also really appreciate how you work through so many examples in each of your videos. Keep it up, you are doing KZfaq and ochem students everywhere a great service!

Zuko is teaching me Organic Chemistry!

The lightbulb above my head just turned on. Thank you.

how is the left side and the right side of the cyclopentane the same??

omg wish you were my professor!! i would had failed chem without you in youtube

Keep making such great videos! Really helpful!

Wow, this is very informational and easy to understand. Thank you!

Finally, I can find how many chiral centers are in bond. Thanks for teaching us

explained the thing just in a moment. Thanks a lot sir.

Wow, you just saved one Korean student. So easy to understand!!!!!!

wow thanks for the explanation!! actually my finals in a few hours lol

3:24 we can just say it's achiral by the plain of symmetry

did not teach well for the last example

Easy trick guys...first just look for carbons with three separate bonds

Thank you so much! This video is so explanatory. Absolutely Phenomenal :)

Very useful for easy learning thank you so much

My textbook did such a crap job explaining this. I'm sitting there seeing an indicated chiral center that's attached to a hydrogen, a ch2 a ch2 and an hydroxide trying to figure out how ch2 and ch2 are different groups. It failed to explain that everything else attached to each carbon constitutes as a group. Thank you so much!!!

It became very easy after you explained🤩🤩 Thank you ✨💯

I still don't get it

At 4:22 How are they the same? Its not symmetric. So it has to be counted as 2 diff grps right?

Great video! Helped to clear up the confusion I had before. You're the best!

you've got a really nice voice mister. thanks for the vid

THE ORGANIC CHEMISTRY TUTOR ❤❤❤

Thank you!

This was a lifesaver

can u explain again the last example plz

It was really very helpful.

Your explanation is nice

Thanks for your video. I just have a question. Can molecules with benzene ring in them have chiral centres in the benzene ring? Like at the point where there is a branch coming off the ring?

explanations weren’t great

what about the cyclopentane. I don’g agree that there are equals

Why are we finding chiral centers or r or s configs? I am missing the context of why.

Victor should’ve briefed up with this 😭

2:08 isnt the line on top of the 2nd carbon called a methyl group? why did he call it a hydroxyl group when thr is no OH present? plsss clarify

For the second to last example you did in this video (one with cyclopentane, methyl, fluorine, and OH), how can you tell that the carbon in the cyclopentane attached to the OH has two of the same things around it? Is it because there are two carbons (from the cyclopentane) on one side of the carbon attached to -OH and then two other carbons (from the same cyclopentane) on the other side of the carbon attached to -OH?

U ARE A GODSEND

Thanks a lot

At 2:00 please do highlight OH group will bright colours...cuz while the question was being asked.. we could not see the dark blue/purple coloured OH.(unless u turn on ur screen brightness to full mode).. 😊

Pls do a video on pseudo chiral carbon

Thanks this helped a lot👍🏼❤️

Not that he didn’t explain well on the last example. Watch it from the beginning to the end, he assumes that everyone should now know how to explain it by comparing your answer vs. his answer.

Wow...thanks so much Really do appreciate

Superb explanation

Would of loved to hear the explication of the last example but the video cuts off…

Thank you ✨✨✨✨

What about 1,2-chlorocyclohexane?

Oh so I was correct at the last part- I'm learning

Why is there an invisible hydrogen in every chiral center?

THANKS 🥰🥰

At 2:21 if the right and left are the same, then how are they both chiral centers?

What is meant by invisible hydrogen? Where that comes from?

THANK YOU!

Thank you

Bro saved me from an extra mental breakdown

thank you

Thank u so much 🙏💗

Thank you!🌟💥👍💫

can anybody help me out with the name of this compound at 5:16

How many chiral centres r there in Ranitidine , Cimetidine,Bromopheniramine, Iproniazid, Phenelzine,Equanil ,Serotonin , Veronal , Valium , Tetracycline , Ofloxacin ..... If u know any of them plz and }:‑)🙏

Thanks 😊🙏

What is the name of the molecule at 4:13 ?

if only u were my teacher

Nice

bro i love you

I thank Jesus for you bro

wtf is the last one

👍👍👍

Thank you!

I owe you my degree man I swear

Thank you (Sun 20 Dec 2020, 6:03 PM)

Thanks girl

Great

i still dont get it whatttttttttttttttt

i keep confusing element with groups 😭

in this video ...

❤️

Not explained very well

Walter White brought me here

fuck this class. thanks for the help but oh dear god this sucks

a center can't be chiral. dislike.
