Thank you, thank you, thank you! I think your way of teaching is super effective, I love the clarity of your videos😃 please make a video on the interpretation of NMR plot of an unknown substance (drug, oil, food...) in which you guess the substance just relying on the plot, without having the chemical formula
What about complex splitting? One group of methyl hydrogens is presented as a sextet, but the neighbors are not all equivalent... Shouldn't the splitting show a triplet of quartets or something (12 peaks)?
because they are in the same environment. each carbon is surrounded by the exact same thing (a CH2 group on both sides) the CH2 by the OH is not in the same environment because it has an OH on one side
I'm not sure if this is what you're asking... but the 2nd CH2 group from the top is next to a group with a carbon that has 3 hydrogens attached to it (the very top C) and another group with a carbon that has 2 hydrogens attached to it (the 3rd C from the top)... thus that group is in a different chemical environment than each of the CH2 groups in the [CH2-CH2-CH2] grouping... the ones in this grouping are considered chemically equivalent because if you look at the carbons adjacent to each of these they are each attached to a carbon with 2 hydrogens attached to it... Again, that 2nd CH2 group was beside one carbon with THREE hydrogens and another carbon with TWO~ Does that make sense? :S I tried haha
I think think these three groups are seperate individual groups, because in this molecule symmetry is absent, and these three groups have different enviroment
I love how he keeps repeating things making you memorize it with him while watching. Just amazing!!
YOU are fantastic at teaching NO ONE IS BETTER that you!!!!
Are you not accounting for the deshielding effects that are caused by the electronegative oxygen?

you are a really amazing teacher! god bless!
Why is a less shield proton group shown upfield?And a more shielded downfield?
Dude I love you
I LOVE YOU DAVE

How did you determine that the 3CH2’s were in the same environment ?
I think I got it! So if they’re bonded to and identical molecule they’re In the same environment
How do you know that CH2-CH2-CH2 is one groups and not 3 separate groups?
because they are in the same environment. each carbon is surrounded by the exact same thing (a CH2 group on both sides) the CH2 by the OH is not in the same environment because it has an OH on one side
ok, but how do you know the 2nd to highest CH2 group is not included with the previous group [the CH2-CH2-CH2 group]?
I'm not sure if this is what you're asking... but the 2nd CH2 group from the top is next to a group with a carbon that has 3 hydrogens attached to it (the very top C) and another group with a carbon that has 2 hydrogens attached to it (the 3rd C from the top)... thus that group is in a different chemical environment than each of the CH2 groups in the [CH2-CH2-CH2] grouping... the ones in this grouping are considered chemically equivalent because if you look at the carbons adjacent to each of these they are each attached to a carbon with 2 hydrogens attached to it...

Wouldn't the hydroxyl oxygen be downstream of everything else? And would it be split by its two neighbor protons since the adjacent atom is a carbon?
THANK YOU!
Thank you! ❤️
You’re missing splitting, deshielding and peak concepts in the video
Good
