Chapter 12.15C, Problem 12.11P

Interpretation Introduction

Interpretation: The peaks at $\text{m}/\text{z}$$87,111$ and $126$ in the mass spectrum of $2,6-\text{dimethylheptane}-4-\text{ol}$ are to be accounted.

Concept introduction: Mass spectroscopy provides a reliable molecular weight for an unknown compound and also gives us the information about the molecular formula as well.

Fragmentation gives the resonance stabilized cations whenever possible. Loss of a small molecule is usually indicated by a fragment peak having an even mass number corresponding to loss of an even mass number.

To determine: The peaks at $\text{m}/\text{z}$$87,111$ and $126$ in the mass spectrum of $2,6-\text{dimethylheptane}-4-\text{ol}$.
