Organic chemistry analysis of THC

Question

Identify the chiral centers located within tetrahydrocannabinol, designate which centers are R/S, and explain why each center is R/S.

Bonus: Theoretically, if you could change ANY of the chiral centers in marijuana; why would this possibility change the psychoactive effect?

Answer 1

I posted a video reviewing how to find chiral carbons, the rules for labeling as R or S, and then showing how the rules are applied to THC at this link:

Answer 2

Bonus Answer: If you change ANY of the chirality centers in THC, it would not be able to “fit” properly into its unique biological enzyme receptor , which in turn produces a biochemical cascade that gives the euphoria and other side effects associated with the molecule. Think of it like this. To get the psychoactive effect it’s like a key unlocking a door. The key is the THC molecule. The door is your mind. Just as if any key was altered only slightly , then it would be quite difficult if not impossible to open said lock.
