Are you trying to understand 1H-NMR in your Organic Chemistry class?
Awesome! You came to the right place! Oh…and thanks for stoping by!
NMR is topic that comes up pretty quickly after you start your second semester of OChem. And I know it can appear to be a beast.
But don’t worry! It is a gentle giant.
A good place to start is with the n+1 rule
We don’t need to jump in head first and tackle something complicated. Let’s start simple.
Here is a small organic molecule that will be great to start with…
OK – Let’s being with the CH3 on the left. It has one neighbor (CH2) with two green hydrogens.
If we use the n + 1 rule, we will get 3 (2 + 1). This means that the three red hydrogens will be split into a triplet.
Next, the CH2 has two neighbors but only one of them has hydrogens.Therefore, they will be split into a quartet (3 + 1 = 4).
Lastly, the CH3 has one neighbor…but no hydrogens. So, it will only show up as a singlet (0 + 1 = 1).
This is pretty awesome! But are you looking for more?
Don’t worry…I got you covered.

Keep being you! And keep being awesome!
Awesome method for explanation of Hnmr signal.
Thank you 👍👊💥!
