AQA A-Level Chemistry - Carbon-13 NMR

This video gives a little bit of background for carbon-13 NMR, including the use of TMS and deuterated solvents (more on both of those are covered in the proton NMR video), followed by how to interpret carbon-13 spectra.

LOOOL my exam is today and im still learning content

[naomibarretto]

For the millionth time, I can't thank you enough, yoU AMAZING HUMAN BEING. You have saved me countless number of times when I was on the verge of giving up and failing. I CAN'T EXPRESS MY GRATITUDE. I HAVEN'T EVEN STARTED THE BLOODY VIDEO AND I AM ALREADY SO HAPPY THAT THIS IS ON HERE. ANALYTICAL DOESN'T MAKE ANY SENSE AT ALL

Your an absolute Legend. Thank you so much. Just watched the proton NMR and that video was amazing. It's pretty neat that you include hard exam questions at the end, it shows you how these topics are phrased in exams. Extra prayers for you man. 🙏🏽🙏🏽🙏🏽

MY GOAT. I hope you are Well Sir Erintoul. I and so many others say Thanks. Keep smiling.

I'm studying Unit 4 for my mocks and I find this so difficult to get to grips with. Lovee your style of writing and you explain it so clearly. Thank you and I hope you will make more A2 videos! 

[lzrwimv]

boss you yeno lad. proper love ye is right you fuckin gem

[kingbaldy]

Brilliant video, shed light on this topic that I had no clue about cheers!

E rintoul "You dont need to know this"

[staceysibbs]

Tuning your radio “guhhhh”😂 6.41 I will remember that in my exam

I don't understand why TNT has 5 peaks, the bottom carbon is bonded to 2 carbons and a nitrogen as well so i though it should be in the same peak with the other 2.

[monmatal]

this is brilliant easy to follow stuff. I was brushing up for an interview thanks

[waffleamv_]

27:25 would the bottom carbon of the benzene ring not also have the same environment as the other ones bonded to NO2?

[modelaircraft]

fantastic video!, best video explaining NMR!

[alibrastar]

I have fallen in love with your handwriting... honestly it's immaculate!!!  

[ephemeral]

These videos are sooo helpful! thank you! As far as revision goes, what techniques would you suggest to make sure you're getting high marks once you've learned the content?

Thanks again!

Just slightly confused about the 1-methylethylpropanoate - I thought there were only 4 peaks as the first CH3 of the "propan" part is identical to the last two CH3 groups of the methyl and ethyl. So aren't all the CH3 groups in the same environment and they all count as one peak??

[scienceplease]

Can't thank you enough! I think I've got it! thanks for the tips on the symmetry as well

[adammcgrath]

These videos help me so much, saved my grades hahaha

[travelconnoisseur]

I am a bit confused about 21:45 - isn't what you have drawn 2-methylethyl propanoate (seeing as the methyl group is coming off the 2nd carbon from the right end)?

Surely 1-methylethyl propanoate doesn't exist considering that a methyl group coming off the 1st carbon is basically same as calling it proply propanoate?
