Скачать или смотреть HNMR: Comparing Alcohol and Ether isomers using Low & High Resolution spectra

In this video learn how to identify between three isomers:
propan-1-ol, propan-2-ol and methoxyethane .

To do this we look at:
1. the number of proton environments
2. Low resolution HNMR
3. High resolution HNMR

Proton nuclear magnetic resonance spectroscopy (proton NMR or 1H NMR) can give information about:

1. the different chemical environments of hydrogen atoms (protons or 1H) in an organic molecule
2. and about how many hydrogen atoms there are in each of these environments.

In a high-resolution 1H NMR an interaction with 1H atoms on neighbouring carbon atoms can result in the splitting of peaks into multiplets.

The number of 1H atoms on neighbouring carbon atoms will determine the number of peaks within a multiplet and can be determined using the n+1 rule, where n is the number of 1H atoms on the neighbouring carbon atom.
