1H NMR spectrum of a compound with molecular formula C4H9NO2 shows:d 5...
Given information:
- Molecular formula: C4H9NO2
- 1H NMR spectrum:
- d 5.30 (broad, 1H)
- d 4.10 (q, 2H)
- d 2.80 (d, 3H)
- d 1.20 (t, 3H)
To determine the structure of the compound, we need to analyze the 1H NMR spectrum and use it to identify the different types of hydrogen atoms present in the molecule. We can then use this information to propose a structure that is consistent with the observed spectrum.
Analysis of 1H NMR spectrum:
- d 5.30 (broad, 1H): This signal is likely due to a hydrogen atom attached to a nitrogen atom or an oxygen atom. The broadness of the peak suggests that it is a hydrogen that is exchanging rapidly with other hydrogens in the molecule, which is characteristic of an NH or OH group.
- d 4.10 (q, 2H): This signal is likely due to two hydrogens that are attached to the same carbon atom. The fact that it is a quartet (q) suggests that the two hydrogens are coupled to each other and to another nearby hydrogen atom.
- d 2.80 (d, 3H): This signal is likely due to three hydrogens that are attached to a methyl (CH3) group. The fact that it is a doublet (d) suggests that the three hydrogens are coupled to a nearby hydrogen atom.
- d 1.20 (t, 3H): This signal is likely due to three hydrogens that are attached to a methyl (CH3) group. The fact that it is a triplet (t) suggests that the three hydrogens are coupled to each other and to two nearby hydrogen atoms.
Proposed structure:
- Based on the above analysis, we can propose a structure that is consistent with the observed spectrum:
- CH3NHCOOCH2CH3
- In this structure, the hydrogen atom responsible for the broad peak at d 5.30 is the NH hydrogen, which is exchanging rapidly with the nearby CH3 hydrogen atoms. The two hydrogens responsible for the quartet at d 4.10 are the CH2 hydrogens that are coupled to the nearby CH3 and NH hydrogens. The three hydrogens responsible for the doublet at d 2.80 are the CH3 hydrogens that are coupled to a nearby CH2 hydrogen. The three hydrogens responsible for the triplet at d 1.20 are the other CH3 hydrogens that are coupled to two nearby CH2 hydrogens.
