Concept explainers
Interpretation:
Which spectroscopic method could be used to distinguish among the three isomeric acids, pentanoic acid, 3-methylbutanoic acid and 2,2-dimethylpropanoic acid, is to be stated. The characteristics features expected for each acid in the spectrum are also to be stated.
Concept introduction:
1H NMR can be used to distinguish these isomers. By observing the signals due to the methyl group(s) present (the number of protons giving that signal and its spin multiplicity) in these three compounds they can be distinguished.
To state:
Which spectroscopic method could be used to distinguish among the three isomeric acids, pentanoic acid, 3-methylbutanoic acid and 2,2-dimethylpropanoic acid, is to be stated. The characteristics features expected for each acid in the spectrum.
