H-NMR Predicting Molecular Structure Using Formula + Graph

This video walks you through the basics of solving a proton NMR practice problem when presented with a molecular formula and NMR spectrum starting with calculating index of hydrogen deficiency, identifying the nature of each peak on the graph, and finally connecting all the puzzle pieces for your final product.

You're the best. I was struggling trying to understand from my professor but you made everything much easier to understand- love the color coding!

[ankitaprakash]

This is the best explanation I have seen thank you!

[qcqlulq]

Your videos get me through orgo! When I sent you my syllabus I didn’t know you would respond with a video so fast! Thank you much! 🙌🏻🙌🏻🙌🏻

[ruwaydaomar]

Thank you very much! your short video helped me understand more than I could in my class's 1 hour lecture video.

Leah, I don’t know if you will see this but you are actually the best. I hated organic chemistry I, but I decided to start spending a lot of time reviewing for organic chemistry II. And your videos have helped TREMENDOUSLY. thank you for that. I love you.

You are teaching awesome with very simple method. Anyone can catch it easily. And thanks

I took a electrodynamics physics course so this material came fast and
easy to me. If you understand resonance and the effect on a magnetic
field that a moving charge has in space, then the basic concept around
nmr is only a "real world' application to said theory. However, the
multiple examples that are present regarding functional groups and those
that go against normal intuition are needed to be studied. You managed
to put all those in a nice simple package. Thanks!

This is a clear explanation, I wish had know about these earlier.

[Fatherfkkrs]

Make more spectroscopy videos for us professor!! And thanks for this video.

[inotetsu]

This video taught me more than 3, 2 hour lectures.

mind blown - its all coming together thank you

[siddharthdave]

you are literally the best. Thank you SO MUCH

Friendly tip for those who are solving with area: The area is a solved integral for under the peak of the graph. In order to find the number of hydrogens corresponding to that peak, just sum up the entire area of the graph, and then multiply by the integer for which you want to find out the number of hydrogens. Took me 6 hours and a lot of nerves of why i can't solve a simple H-NMR...

Thanku Leah for clearing my doubts you're awesome 👌👌👍

[asuasonia]

Thank you Leah. You made it very simple and concise

[vandoannn]

Thank you for helping me through ochem this semester!!

[martinarenzi]

Thank you so much! I have watched all this playlist and found it extremely clear and helpful 😃 please make a playlist also on UV Vis, IR and other spectroscopic spectra😃

[ekeomabernardchukwuemeka]

Spectacular tutorial. Really great!!!!

[luizfarias]

This video helped me so much! Thank you!

Thank you for making the video. A question: how do you know the 1H, 1H, 2H, 6H, 3H at the beginning?
