What do H NMR peaks mean?
The number of peaks tells you the number of different environments the hydrogen atoms are in. The ratio of the areas under the peaks tells you the ratio of the numbers of hydrogen atoms in each of these environments.

Is phenyl acidic or basic?
Why is phenol acidic? Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring.
What information does H NMR provide?
H NMR is the go-to technique to help identify or confirm the structure of organic compounds or those that contain protons. A solution-state proton spectrum is relatively fast to acquire, compared with other nuclei, and a lot of information about the structure of a compound can be deduced from it.
Where do alcohols show up on H NMR?
H Nuclear Magnetic Resonance Spectroscopy Protons on carbon adjacent to the alcohol oxygen show up in the region of 3.4-4.5 ppm. The electronegativity of the alcohol oxygen de-shields these protons causing them to appear downfield when compared to alkane protons.
What determines number of peaks in NMR?
The number of peaks shown by a compound in proton NMR depends on the presence of magnetically non-equivalent protons in the compound. So in order to predict NMR spectra, we should count protons with different magnetic environment.
