Concept explainers
The mass spectrum of the following compound shows fragments at

Interpretation: The structures of the ions of a given compound that shows fragments at
Concept introduction: Molecular ion is the radical cation which is formed by ejection of electrons from a molecule when a beam of high-energy electrons bombarded on a molecule. Mass of the molecule is equal to
Answer to Problem 15P
The fragments of 3-ethyl, 3-methylheptane at
Explanation of Solution
The ball and stick model of the given compound is,
Figure 1
Black colored atoms have four bonds. So, these are the carbon atoms. The grey colored balls have one bond. So, these are the hydrogen atoms. The molecular structure is,
Figure 2
Hence, the ball and stick model of the given compound is 3-ethyl, 3-methylheptane. The mass of 3-ethyl, 3-methylheptane is follow.
Thus, the molecular ion peak of 3-ethyl, 3-methylheptane is observed at
The molecular ion
The molecular ion
The molecular ion
Hence, the fragments of 3-ethyl, 3-methylheptane at
Figure 3
The fragments of 3-ethyl, 3-methylheptane at
