Interpretation:
The structure of the compound with molecular formula
Concept introduction:
Mass spectrometry is a technique used for measuring the masses of atoms and molecules with great accuracy.
In a mass spectrometer, the vapor of organic compound is bombarded with a beam of high energy electrons that makes the neutral molecule lose an electron and converts it to a radical cation known as a molecular ion.

Nuclear Magnetic Resonance (NMR) is one of the most capable analytical techniques used for determining the functional groups and how the atoms are structured and arranged in a molecule.
Few elements, such as
In
Induced magnetic field consists of electricity generated from movement in a magnetic field.
The position of a signal on x-axis in the
The number of signals in
The area covered by the signal is proportional to the number of equivalent protons causing the signal.
The hydrogen atoms on adjacent carbon atoms split the signal into two or more peaks. One, two or three hydrogen atoms split the signal into two, three or four peaks described as doublet, triplet or quartet respectively.
A decrease in the electron density around a proton deshields the signal downfield at a larger value of chemical shift.
An increase in electron density shields the signal upfield at a lower value of chemical shift.
