Question

NMR spectra for two compounds are given here, together with the molecular formulas. Each compound is a ketone or an aldehyde. In each case, show what characteristics of the spectrum imply the presence of a ketone or an aldehyde, and propose a structure for the compound.

David · Accepted Answer

Answer :- the structure of the compound with molecular formula C
8
H
8
O whose spectrum is given 13C NMR . So this compound contain the aldehyde
group because in 13C NMR around 200 chemical shift is due to -CHO group . The structure is gives as follows.
