Interpretation Introduction

Interpretation:

The number of peaks appeared in the NMR spectrum of each isomer of ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}$ and ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$ has to be given.

Concept Introduction:

In NMR spectroscopy, the protons with identical carbon atom environment produce one peak and protons with different carbon environments produce different peaks.

In NMR spectra, the peaks are formed due to coupling of protons of one carbon with protons of adjacent carbon atoms.
