How do you know which hydrogen on Camphor belongs to
which peak in H NMR
Homework Answers
The most shielded peak at 0.85 ppm is by the methyl on 7th carbon which is on the side of carbonyl group.
the next peak at 0.9 ppm goes to the methyl adjacent to carbonyl carbon. and the next less shielded one can be assigned to the methyl on carbon -7 which is away from the carbonyl group.
your spectrum shows some extra peaks, there need to be three peaks only corresponding to three methyl groups in 0.8- 1.0 ppm

How would you be able to identify this compound based on its H
NMR spectrum?
I do know based by it's shift (ppm) it'll have a benzene ring as
well as an aldehyde. An explanation would be helpful, thank
you.
