In minute 17:00 shouldn't there be 9 chiral centers and not just 8. I am referring to the carbon under the second carbon that you numbered. Isn't that also a chiral center since it is attached to 4 different groups?

TY, I appreciate all your hard work. I watch many of your videos and they have helped a lot! ***Possible CORRECTION? looks like the cholesterol molecule in your video has the double bond in the wrong place. *** I kept going over and over this and could not understand why Carbon-5 (the one due south of the methyl group) was not a chiral center? As the figure is drawn, it should be...which would make 9 stereocenters, not 8. But when I looked up cholesterol, the double bond is actually between C-5 and C-6 not as you've shown it. Just in case anyone else got stuck on this problem.

He made a small error and drew the double bond in the wrong place. So, you're right that the molecule shown has 9 stereocenters! In reality, cholesterol only has 8. You can confirm this by googling the molecule. xx

Another incredible video; thanks so much for posting! If the hydrogen (or lowest priority group) isn't where I want it to be, sometimes I just exchange two groups to make that happen, and remember that that inverts the stereochemistry (R -> S or vice versa).

Would definitely like to see the face behind the man behind my success. The organic chemistry tutor has helped me Ideally with statistics, Calculus, a bit of genetics, general chemistry, Physics and organic chemistry ❤️

When identifying the chiral centers on cholesterol, I think you accidently missed one and it would be 9 instead of 8. Isn't there a chiral center on the carbon below the one you indentified as 2?

@XQJimmy

You are right! Based off of his structure, there are 9 chiral centers. However, the double bond in his cholesterol drawing is in the incorrect position; it should be moved one spot to the left. After that change, there will only be 8 chiral centers

I thank this man for passing me for my organic chemistry sub. I owe a lot to you ❤

Thank you so much man you really made me do problems in chemistry with such nice understanding and knowledge I really used to hate doing problems but because of you it has eventually become easier ❤❤❤

For Q3, the one assigning chiral centers for Cholesterol, would there not be a chiral carbon just below the 2nd chiral carbon? It is attached to a sp2 hybridized carbon, the carbon with a methyl group, and a ch2 carbon that eventually leads to an alcohol

Yes, he drew the double bond incorrectly, the two cicle hexanes are supposed to be "fused" via a double bond between the carbon under chiral carbon 2 and the carbon to it's right, so in the cholesterol molecule there are only 8 chiral centers, but the molecule shown in the video has 9 chiral centers.

That trick at the end with the triangle and the circled number was mind-boggling haha. That makes it so much easier, thanks!

The position of the C=C in cholesterol is wrong, according to your drawn diagram, there should be 9 chiral centers, but for cholesterol, there is only 8 because of the positioning of the C=C. But other than that, I loved the video and it helped me a lot in understanding stereochemistry.

When you explain chiral centers in cholesterol, there is an error in cholesterol at 17:17. The double bond should be on Carbon 5 and 6 not on 6 and 7.

In problem 3, why is the tertiary carbon closest to the double bond not considered a chiral center? I am talking about the bottom right carbon on the farthest benzene to the left of the cholesterol.
