Chemical and magnetic equivalence

[@vikramjoshi3452]

Thank you ma’am. I couldn’t understand this concept for a long time and no one was able to explain it either. This video clears it up, thank you.

Better concept in only 3 minutes , Thanks mam

Thank you so much, Mrs. Harding!

[@ohyoucanread]

It finally makes sense ! Thank you very much

Thanks for the feedback, I’m glad you found it useful!

do chemically equivalent but magnetically inequivalent protons (e.g. A, A') couple to each other? ive read sources where it says they do, but they werent coupled in your example.

[@ru1h]

In the example for the para substituted ring why doesn’t Hb magnetically couple with Hb” (meta position) and (Ha and Ha’) they are only 4 bonds away from each other and isn’t long range coupling allowed for rings

[@lindsayharding8930]

Hi, in that example, Ha and Ha’ are in the same chemical environment as each other, and Hb and Hb’ are also in the same chemical environment as each other. Protons in the same chemical environment won’t couple together as they are effectively the same proton. Hope that helps!

Oh my gaahh thanks
