"To be NMR-active, a nucleus must have a non-zero nuclear spin (I ≠ 0). It is this non-zero spin that enables nuclei to interact with external magnetic fields and show signals in NMR. Atoms with both an odd number of protons and an odd number of neutrons, or an odd sum of protons and neutrons, exhibit half-integer values for the nuclear spin quantum number (I = 1/2, 3/2, 3/5, and so on). These atoms are NMR-active because they possess non-zero nuclear spin."

- I think the amount that NMR active nuclei possess a non-zero nuclear spin is said too many times.

- Also citations are required

"H1 graphs demonstrate the placement of hydrogens, which senses the effect of electron-withdrawing groups (EWG) and electron-donating groups (EDG). (Source)"

- I think the H1 should be 1H, also I think a more appropriate word would be 1H spectra.

"Another benefit to NMR is the measurement of J coupling, which allows for the detection of zusammen (Z) or entgegen (E) conformation. (source)"

- I think the J coupling value can also give information on adjacent protons, not just the Z or E conformation.

- should also hyperlink the Z and E conformation.

1H NMR graphs should be replaced with 1H NMR spectra.

"This movement of electron density is due to the structure using resonance. There are three positions a molecule can add in six-member rings, Ortho, Meta, and Para:"

- you can also add to the immediate position. Source would really help here if this the claim is true.

"Characterization of EWG is acknowledged, as it forces molecules to add in the Meta position on ring structures, while EDG groups allow molecules to add Ortho or Para."

- I don't know if this adds to the article. I think if you're going to talk about electrophilic aromatic substitution maybe add more detail, or instead use hyperlinks to your benefit.

The images used are good, though for the proper draft images made in chem draw would be more professional.

Overall the draft contains a lot of good information. Though with the addition of citations it would carry more meaning. This article would also benefit from a quick review of necessary content for the article so that your not covering things that distract from the main purpose of the article.

It is obvious that the authors are quite well versed in NMR but with citations this would be made much better!

Way to go guys!
