How many 1 HNNMr signals would you predict for each of the following compounds?

Question:

How many 1 HNNMr signals would you predict for each of the following compounds?

Reading a NMR spectra.

The chemical shift is the definitive indicator of the electronic environment surrounding a hydrogen nuclei within a molecule. The value of chemical shift of a H-nuclei generally rises with the deficiency in the electron density of its surroundings and vice-versa. But this general trend may be abruptly affected by paramagnetic/diamagnetic anisotropic effects. While correlating a NMR spectra to a structure, the first thing to recognize is the number of different signals that are expected from the structure.

Answer and Explanation:

Two separate H-nuclei in a molecule which appear at the same value of chemical shift are called Isochronous while those that appear at different...
