Many thanks. This is eye-openng.

[@temangwenizwane336]

very helpful, thank you.

[@naufahanif1996]

thank you very much Prof! such a brilliant lecture video, sir!

[@ChemComplete]

Many thanks!

[@sushmitasingh3326]

What will be the compound with molecular formula C6H14O that gives only 2 NMR signals?

[@taylorp6141]

This is one of the best spectroscopy videos I've watched. I just purchased the guide from your website - it is GOLD! Thank you!

[@ChemComplete]

Awesome, thank you!

[@congnghebandan]

Great lesson! Thanks alot!

[@fakhrulnawawi9681]

I completely understand this video. Thanks

[@rtk-j23]

this is a super explanation. thank you so much

[@andrewpritchard2863]

So why is the CH3 further up field if it’s near the carbonyl? So wouldn’t that triplet on the H NMR be further down field?

[@jonathansanchez8802]

great stuff!

[@maxwellkeicha9418]

Thank you very much.

[@ChemComplete]

You are welcome!

[@safiabegum6826]

Well done sir.

[@matteomarchesi507]

why it couldnt be an amide?

[@riki8426]

Lifesaver!!

[@niloofarkh4779]

thank u

[@kylecatman7738]

Also the 3 carbons without Hydrogens is accounted for

[@Katie-g3u]

Please please could you do the C7H7NO one?

[@ChemComplete]

Hi Katie, C7H7NO is a molecular formula that could have multiple structures. If you send me the spectra (NMR IR, MS) that you have I can look them over and present them as a video on the channel. If not try putting the formula into google and seeing the various structures that come up. I know benzamide is a VERY common organic compound with that formula. If you have aromatic peaks in the HNMR, a carbonyl in the IR and an NH2 in the IR/NMR then it likely could be that.

[@Katie-g3u]

Thank you :) I have emailed the spectra to you

[@julian444]

Good explanation for sure, our exams are always without chemical formula however, do you have any video's without the formula given

[@mattsoutback59]

I wish my professors added mass spec and DEPT NMR, we did bare bones HNMR and CNMR. Great series! Thanks a million!

Greetings from Istanbul, Turkiye. Teşekkürler.

[@jaydenarifpardy2049]

you are a king

[@alejandrobonilla813]

Thank you so much. As a premed, you make ochem UNDERSTANDABLE. You have literally helped me earn a 95% on my first ochem II quiz. Tomorrow 2/28 is exam 1 for me... I will keep you posted

[@ChemComplete]

Fantastic! So many premed students fear organic chemistry, but if you understand the basics it is much more approachable.

[@blessingfava4011]

great. thank you

[@zeinebkhlifi4343]

thank you very helpful please keep on posting such videos

[@harrypoutter3224]

How do you determine organic structure if structure formula is not known ??

[@ChemComplete]

When the structural formula is not known you utilize all other spectra to support your argument. The information we get from the molecular formula is the degrees of unsaturation. This information helps us, but the structures can be solved without it. I will agree the process becomes more annoying without it, but still possible.

Im having my finals soon and this was awesome!!!! I do appreciate you!!!🎉🎉🎉

[@MrKola09]

Awesome lecture

[@user-be4yc2vr5c]

This was really great thank you. Enjoying this very much and very helpful.

[@ChemComplete]

Thank you for all the support and feedback!

[@matthiasschwier3875]

did i missed somthing or why there are only 4 doublebounds not 5 ?

[@ChemComplete]

There are 5 degrees of unsaturation, not 5 double bonds. A ring system accounts for one of the degrees of unsaturation, the rest are due to double bonds.

[@shazich9807]

Kindly upload combined spectra problems no 51 52 53 54 55.
