Optical Activity - Specific Rotation & Enantiomeric Excess - Stereochemistry Youtube
This organic chemistry video tutorial explains how to calculate the specific rotation of an enantiomer given the observed rotation, the pathlength, and the concentration of the solution. It discusses how to determine if a molecule will show optical activity based on its chirality. It also provides the formulas needed to calculate the optical purity and enantiomeric excess. Those formulas can be used to calculate the relative percentages of the R and S isomers.

Thank you man you literally saved my life I watched your video and I succeeded unbelievably 👍👍👍👍👍
English isn't even my first language and I understand your videos better than my own teacher. Thank you, you saved me from freaking out over this topic.

How does rotation occurs in optical isomerism or optical reactivity?
I love you 😭😭💓 you're a life saver I swear

Hi Mr organic chemist please can I have a video on Jacobians in maths and hiw to find limits in tripple integrals before I calculate the integral
Some text book says: : R - configuration rotates in a dextrorotatory way : and other say R - configuration rotates light in a levorotatory manner Help clarify this for me Thnx🤗

That's why he said the r configuration is not always associated with the (+) it can be either left or right same thing as the s configuration

Depends on the specific molecule u are dealing with
Please do a video on symmetry operations 🙏🏽

For question 2 (at the end of the video) I got alpha = -1.386*10^6º.

What does "rotate light" mean, from a practical perspective? What does it look like?

Hello, I'm a member, can you please help me? Do truxinate dimers which have a cyclobutane ring and either 2, 3 or 4 substituents on the same face have enantiomers? Sorry, just something I need to prepare and can't find the answer for!
when we rotate the trans-1,2-cyclohexanediol, does that make the molecule achiral?

How to you rotate light? ? Tooo much confusion with this topic.
Woudld be awsome if you could have the transcript written out

so how do we know if it's (+) or (-)?
