Ans:
The assignment and possible structures of all the four NMR spectra are attached. The correlation was made by the number of protons and the splitting pattern and also the chemical shifts observed in all the provided 1H -NMR. The assignment of all the magnetically equivalent protons are assigned with the same letter, like a, b, c etc. The identification of all the four compounds are as follows:
4-a: Iso-propanol
4-b: Pinacolone
4-c: 1-bromo-2-methyl propane
4-d: p-Toluonitrile
