1. I think the very first step should be measuring the degree of unsaturation. 2. For ensuring which one is e/f, you can go for chemical shift calculation.

Man, I just found your videos and they are really good, you talk very clearly and show every step of the thinking behind the problem. I was searching for videos like that so I could see someone actually working on determining structures from spectra and it helped me a lot. About the UV, it's probably just confirming the existence of conjugation, I think. The more conjugated the molecule, the higher the max wavelength it absorbs in UV-VIS region. The spectra shows an absorption at 260 nm, so it must have some conjugation, but not too much as it falls in the UV region, not in the VIS.

2:30 that’s something called “overtone” created from the carbonyl

This was really helpful thanks, maybe running through how to get the Molecular formula when you don't have it would be a plus

The small peak at 3400 in IR is the overtone from the carbonyl.

It's quite brilliant!!! Thank you for sharing. Regards from China

The peak at 122 on MS is called a McLafferty rearrangement and it includes a loss of a whole molecule ( a neutral molecule fragmented off). 😊

This video was very helpful! Thank you for sharing your wisdom and time!

God bless you....I’m now loving organic chemistry 😊🎉❤

My only criticism is that it would be nice to see the NMR data listed out....2H (triplet), etc. along with the actual chemical shift data.

That was pretty helpful. Though you can note that an odd electron ion or an even mass fragment (here it’s at m/z 122) formed through fragmentation of an even mass molecule would result from a rearrangement. This rearrangement here is McLafferty concerted rearrangement that would happen when a gamma sp3-hybridized carbon has a hydrogen atom that transfers to the heteroatom (here it’s the oxygen) with alpha-beta bond to the double bond being cleaved. Note that for an ester it’s a special case rearrangement considering the oxygen atom of the alcohol chain to be alpha with respect to the double bond. Hope this helps.

thanks for your useful video. I will have an exam on friday, this video is awesome

Very helpful 😊😊😊I'm like Organic is my favorite right now 😊🔥🔥🔥💃💃💃

i have confusion about CH splitting ?? ....

Matur nuwun nggih pak. Kula dados ngertos amargi panjenengan 😊

Thanks for sharing, it helped me a lot!!! regards from Spain!

Good explanation, thank you Sir

good young man , wish for you all the good

hi, it would be really useful if you could include pdf of those chart

Really a great video! Thanks!

It was very nice lecture.

This doesn’t explain why you think the ways that you do! During the video you should be explaining why you came to those assumptions

That is a very usefull video thanks from Türkiye💌💌💌

Thanks...good structure determination detective work...cheers

Thank you

The peak you are wared about around 3350 is the overtone of C=O

This is really helpful thank you so much sir

Thanks

Sir also include CNMR spectrum with these two spectrums

It seems you did not assign the carbonyl carbon in C-NMR!

Hello sir I'm from Pakistan..I want to ask about the solving all the spectrum with concluding result..I mean I want to use iR,HNMR,CNMR and Mass spectrum to conclude structure

thanks from india

Sir i have an NMR data of my sample can you interpret it?.

Thanks a lot, Sir

hello can I get you chart for IR and H NMR or all what you have ?

the aromatic region should show 4 lines instead of 3 ?! 1 more for the carbon connected to the ester carbonyl?!!!

I need some help, Is there anyway I could communicate with you Tony?

Hi sir This is Dipak from india Please give examples on TOCSY AND COSEY Spectra

THANK YOU:D

Please solve on C14H15N
