Interpretation Introduction

(a)

Interpretation: The number of peaks for each indicated proton is to be predicted.

Concept introduction: The number of NMR signal in a compound is equal to the number of chemically non-equivalent protons present in that compound. Protons which are present in the same chemical environment that is between the same group of atoms are known as chemically equivalent protons and in ${}^1\text{H}-\text{NMR}$ all chemically equivalent proton generates one signal or one peak, whereas non-equivalent proton generates different signals.

(b)

Interpretation: The number of peaks for each indicated proton is to be predicted.
