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.

How does rotation occurs in optical isomerism or optical reactivity?

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🤗

@user-ol6nn1jx4b 8 ай бұрын

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

@user-ol6nn1jx4b 8 ай бұрын

Depends on the specific molecule u are dealing with

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!
