15.3 The Number of Signals in Proton NMR | Organic Chemistry

[@gabrielgonzales9619]

You helped me immensely with my tests last semester, and you're still coming in to help this semester. Appreciate how you review content learned prior to ensure clarity. Your playlist blesses me

[@ChadsPrep]

Great to hear, Gabriel!

[@Aya-wv3rt]

this stuff actually makes sense to me now. Thank you so much!

[@ChadsPrep]

You're welcome Aya! Nothing I like to hear better!

[@vickyzesu]

Last example is kind tricky but thank you for this vid!! Makes everything so much easier!

[@ChadsPrep]

Thanks - glad to hear it!

[@dulapeep3198]

your video on this topic is the besttt on youtube cant thank you enough liked and subscribed

[@ChadsPrep]

Thanks and welcome, irem!

[@ahmedtaha6431]

Thanks a million ❤❤

[@ChadsPrep]

You're welcome

On the second to last example, why do the top two Hydrogens not count as the same environment?

Thanks for stopping by, Joey!

[@ele1751]

So, even if the second compound (2-bromoprophane) doesn't contain an element of symmetry (because the H and the Br doesn't reflect to each other), I can consider the three hydrogens of the -CH3 homotopic? Have I understand well? Thank you very much for this video!!!

[@KhadijaPatel21]

I've understand this concept now

[@ChadsPrep]

Glad to hear it

[@wenz5854]

ugh in first year OCHEM they dont care about ringed sp3 not being able to rotate. I was doing them like how you did but apparently its wrong for first year ochem

[@RobisonEmanuel-d2f]

You Break it down

[@ChadsPrep]

Happy Studying

[@abdoulazizdabo9064]

Thank you ❤

[@ChadsPrep]

You're so welcome ❤

at 7:57 why did you group the wedged and dashed hydrogen together, whereas on the previous sample you separated and had 7 signals, but here 3. If you had done the same as in last example, you'd have 5 signals, no?

[@ChadsPrep]

So if you check back at the previous example we have Br and H on carbon 1, so there is a Br on the wedge side and an H on the dash side which means the upper and lower surfaces of the molecule have different environments. In this example we have Br wedge and Br dash so the upper and lower face are equivalent. Make sense?

1 year later and this comment actually saved me a lot of confusion. thanks chief@@ChadsPrep
