Organic chemistry 2: from the attached NMR spectrum what can be the proposed molecule that corresponds to the spectrum. Please discuss how how you arrived at the identity of the compound.

NMR: provide the structure of the following molecule.  C5H10O- IR shows a strong, sharp signal at 1700

The molecular weight of the compound is 126.  Deduce its structure based on molecular weight. HNMR,IR, and 13C NMR data provided..

shows five isomers of C5H10O2. The two structures that would be hardest to distinguish by IR spectroscopy are

The DEPT-90 spectrum exhibits 6 in the 0-50 ppm region The DEPT-135 spectrum exhibits x 100 ppm region that is a positive ▾ C6 signal(s) for the CH groups: ▼ 1,2,6 ✓ in the sp2 hybridized region 100-150 C3 and C4 ▼ signal(s) (only the quaternary carbon atoms, signal(s), indicating the presence of a methylene group (CH₂) attached to an oxygen atom, are missing); there is C5 ▼ C1 and C2 ▼ and signal(s) in the 50-

It says that the structure I have here is an incorrect isomer, and I don't know how I need to reconfigure it

Use the 1H NMR and IR spectra given below to identify the structure ofcompound B (molecular formula C4H8O2).

For each set of spectral data, propose an acceptable structure that is consistent with that data 1.. MS: M+ m/z= 84, IR: 2960, 2870, 1734 cm^-1, 13C NMR: 220.16 (C), 38.30 (CH2), 23.24 (CH2) ppm 2.
