The following NMR spectra correspond to compounds of formulas (A) C9H10O2 (B) C4H6O2 and (C) C6H10O2 respectively. Propose structures, and show how they are consistent with the observed absorptions.
Step 1 of 3
From this given NMR spectrum we have to predict the structure of the following molecules:-
(A) C9H10O2 (B) C4H6O2 and (C) C6H10O2
Spectrum A: (C9H12O2)
In H1NMR spectrum, the protons on the C-atom absorb at 3.82 (due to bonding with carbonyl group).
The proton on the -carbon atom absorb at 1.50 because this C-atm is bonded to methyne carbon.
The H-atoms present on the carboxylic acid are most deshielded protons, absorbing at 11.8.
The H-atoms present on the benzene ring absorbs between 7.0 and 9.0.
Hence from this data, the required compound is said to be as 2-phenyl propanoic acid.
In H1NMR spectrum, there is no protons present on the C-atom which is bonded with carbonyl group.The proton on the...
