The number of signals in the 1 H − NMR spectroscopyof the given compoundsare to be predicted. Concept introduction: Nuclear Magnetic Resonance (NMR) is one of the most capable analytical techniques used for determining the functional groups and how atoms are structured and arranged in a molecule. The nuclei of a compound containing protons or carbon-13, when placed under a very strong magnetic field and treated with electromagnetic energy radiation of a suitable frequency, absorb energy through a process called magnetic resonance. Nuclear magnetic resonance spectroscopy is a graph showing characteristic energy absorption frequencies and intensities of a compound under a magnetic field. The hydrogens designated with same alphabets are homotopic, and hence, will have the same signal. The hydrogens that are diastereotopic will have different signals.
