How many uniques 1H NMR and 13C NMR signals exist for each compound?

image

Concepts and reason
The concept used to solve this problem is NMR.
NMR is a major analytical technique which is used for the determination of structure of organic molecule.The nuclei which has odd mass number are NMR active.

Fundamentals
Nuclei has spin and when magnetic field is applied, it aligns itself in the direction of magnetic field and shows signals in NMR spectra.Nuclei in the same environment produce same signal while non-equivalent nuclei shows different signals. image
