Cahn-Ingold-Prelog System?
Those silly chemists misspelled 'Khan"

Mr. Khan, I understood it! Thank you! I like how you explain the little things that sometimes are assumed to be known or to be "guessed", but your detailed explanations are completing the whole picture nicely!

In my chemistry book - the latin word for left and right is Laevus (left,) and Dexter (right). They put D and L in front of the names... It seems both names stand for the same thing. Is these used differently depending on country?

OMB thxx a lot. U explained it soo well

You know what i like about you? you don't assume your students know everything. Where you noted the reason its 1-Bromo-1-Floroethane and not 1-Floro-1-Bromoethane, my Ochem professor would have just named the molecule and if you didnt know why then it just leaves the students confused. Everything is explained as you go when you teach. Its a great way to teach, I really appreciate it.

Hi there, and may I congratulate you for your excellent teaching. Question, from min. 5:00 -> You say that we have to rotate the arrangement so that the lowest group "sits" behind the molecule, and you rotate it using the Br - Carbon bond as an axis... now, would it be possible to use the Methil - Carbon bond as an axis (so that CH3 stays fixed and Br, and H rotate) ? And if possible, would this implicate different results ? Thanks in advance for both your answer and videos!

6:30 not 120, its about 60

@prolarka We're rotating 1/3 of the way around a circle so it would be 360/3 or 120 degrees.
