Question

solution check for proton NMR

Answer 1

I end up with 4 distinct proton environments, so 4 signals?

Answer 2

then for the splitting, using the n + 1 rule

blue = 3 peaks
green = 3 peaks
purple = no splitting, 1 peak
red = 3 peaks

it's been a while since i've done this so sorry if I'm way off >_>

Answer 3

so i'm looking at an actual NMR for this product and apparently there are only three distinct proton environments? why do the aromatic hydrogens all present as one signal?

Answer 4

@tranquility this isn’t urgent but could you take a look when you get a chance?

Answer 5

It's been a while since I've done this too. Maybe they're too close to each other around 7 or 8 so you can't tell that they're different peaks?

Wouldn't green and red have 2 peaks since there's only 1 adjacent hydrogen?
