| solvent | number of peaks | shift |
|---|---|---|
| water | 1 | 1.56 |
| acetone | 1 | 2.17 |
| chloroform | 1 | 7.26 |
| t-butyl methyl ether | 2 | 1.19 |
How many NMR protons are in acetone?
six protons
There are six protons in acetone, and they should all show up near 2 ppm.

How many number of signals are observed in acetone?
Acetone: both methyl groups (two CH3) bonded with C=O. bond, so they are in the same chemical environment, and as a result all the six protons are chemical equivalent that show only one signal.
How many 1H NMR signals does the acetone have in 1H NMR spectra *?
It would be 36 H. There are only six hydrogens in acetone, so it must represent six times as many acetone molecules as there are benzenes.
How many number of signals are observed for acetone?
How many 1h NMR signals does the acetone have in 1h NMR spectra *?
What is the solvent peak for CDCl3?
The proton NMR peak of water changes with respect to the solvent; e.g. 1.56 in CDCl3, 3.33 in DMSO-d6, 0.40 in benzene-d6 etc.
Why is CDCl3 better than CHCl3?
The properties of CDCl3 are virtually identical to those of regular chloroform, although biologically, it is slightly less toxic to the liver than CHCl3, due to its C–D bond, which is stronger than a C–H bond, making it somewhat less prone to form the destructive trichloromethyl radical (•CCl3).
