I don't charge anyone to watch my videos, so please donate if you can to keep me going! bit.ly/scienceshortsdonate
just watched this 5 mins before chem paper 3 and I got the nmr right cuz of this
cold
it's an 18 min video 😂

I've watched multiple videos for NMR and this is the only one which cleared my concepts, thank you so much!!
was helpful!!!
Im sitting my A levels finals 7 days from now hoping an easy nmr question to appear!!!!!
This is better explained in 18 minutes than what my chem lab prof spent 4 hours trying to say. Sheesh, and thank you.
Thanks so much for the great content! I really do think that you should delve into more chemistry in tandem with your amazing physics videos.
Sorry for the reupload!
Thank You for saving my physics preperation, your videos were the only thing I needed to prepare for my A levels.
what grade did you get?
Thank you, sir. This is very easy to understand. I hope you will upload other videos with harder NMR questions :) Every passer-by please check this out!
HA, for a channel named Science Shorts, your explanation sure wasn't lacking in substance! Thanks so much for all that info
This is a really good video! Thank you.
Great video keep it up!
Thank you for the video, it is great!
your voice is so nice
Focus
great video thank you so much
good stuff brother.
Thank you so much ❤
Can't thank you enough 🙏🏻
Lovely. That's an excellent one. Try to prepare some more advanced NMR videos.
Hello, thanks for the great video, it was really helpful. However, I do have a query. At 16:10, where does the peak for the -OH go in the molecule? I didn't really understand that bit, could you please explain? Thank you again.
it's meant to be 0 hydrogen atoms, not OH.
is this for CAIE ? or AQA or something else
8:06 bro said fairly simple, and its gonna get lot lot harder. brudda this was LOT LOT HARDER
7:46 how do u know that there’s another carbon to the right?!?!
because there is supposed to be an alkyl chain but we dont know how long, since there are only 4 carbons, two of which are bonded and another one that is supposed to be in a double bond, that only leaves one carbon hence CH3
thank you daddy
What are you saying?!?!
whyre there soo low views!
nah I give up...this topic just doesn't make any sense
8:06 YOU NEED TO SORT THIS OUT. IN MY 23 YEARS OF LIVING AS A CHEMIST I HAVE NEVER, EVER, IN MY LIFE SEEN A CARBON "DOUBLE BONDED😱😱😨😰" TO A HYDROGEN 🤯🤯🤯🤯🤯🤯🤯 THIS MATTER IS NOT OVER SCIENCE SHORTS UNTIL ONE OF US DIES AND I HAVE NEVER DIED BEROFRE. EMBRARESING
Sorry, where do I say that?
@@ScienceShorts Its written down
@@tomwormell3705 it’s not hydrogen double bonded, it’s C but he’s written H2 next to it because those two H are bonded to the first carbon
@Tom Wormell after spending 23 years as a chemist what are you doing watching an A levels chemistry video?
@@sabeenshahid2024 Clearly, he is looking out for future chemists studying from this channel.
