Concept explainers
(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
Answer to Problem 14.14P
The given compound shows two signals in
Explanation of Solution
The number of signals in each compound is equal to the number of hydrogen atoms present in a different chemical environment. The given compound is
It has two different types of non-equivalent protons shown in red color. Therefore, it gives two signals in
