Question

What is the chemical structure of a compound with a chemical formula of C9H10O2 that shows a signal at 2.3 ppm in its proton NMR spectrum and has a singlet signal at 170 ppm in its carbon NMR spectrum?

Answer 1

Based on the information provided, we can deduce that the compound is likely an ester due to the presence of a singlet signal at 170 ppm in the carbon NMR spectrum, which is characteristic of a carbonyl carbon in an ester group. The chemical formula C9H10O2 also supports this conclusion.The proton NMR signal at 2.3 ppm suggests the presence of a CH3 group adjacent to a carbonyl group, which is typical for an ester.Considering these observations, the chemical structure of the compound is likely to be:CH3COO CH2 7CH3This structure is consistent with the chemical formula C9H10O2, and it contains an ester group with a carbonyl carbon and a CH3 group adjacent to the carbonyl group, which would give rise to the observed NMR signals.
