Question

Even though this is a pure NMR spectrum of the listed compound, the NMR data are not easy to interpret. There are two (2) significant issues/problems/complexities that make a complete analysis of this spectrum impossible: briefly explain using a minimum of words.

I didn't include the H NMR but I'm sure there are a number of things that could be missing, could someone just throw out some non obvious ideas? there are contaminants and I'm wondering if that could be an answer?

Answer 1

Solution :-

The interpretation of the HNMR spectrum can be complex if the impurities are present in the compound under the observation.

The peaks associated with the impurities will give the complex peaks in the HNMR of the pure compounds.

The other complexities with the HNMR interpretation is happen if the spliting pattern of the spectrum is not good that means sometimes we need to take help of the 13C spectrum to figure out the exact structure of the molecule.

the protons which are having nearly same chemical environment shows the complex peaks so resolution of the complex peak is important to determine the exact structure.
