Concept explainers
(a)
Interpretation:
The structure of the compound is to be drawn with the help of details obtained through the NMR spectra.
Concept introduction:
NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is called as a proton in the NMR spectroscopy.
The number of NMR signal in a compound is equal to the number of chemically non-equivalent protons present in that compound. The more the shielded proton lesser will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region or vice versa.
(b)
Interpretation:
The structure of the compound is to be given with the help of details obtained through the NMR spectra.
Concept introduction:
Many nuclei and electrons have spin; due to this spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field.
In NMR spectroscopy, every nucleus has a spin. There is an
