Chapter 21, Problem 21.67SP
Interpretation Introduction

Interpretation: The structure of an unknown compound, its consistency with the observed absorption and fragmentation that account for the prominent ion at m/z 69 and smaller peak at m/z 99 is to be stated.

Concept introduction: A method by which structure of compound is determined by the interaction between matter and electromagnetic radiation is called spectroscopy. A spectroscopic technique in which infrared radiation is used for structural study is called IR spectroscopy.

To determine: The structure of an unknown compound, its consistency with the observed absorption and fragmentation that account for the prominent ion at m/z 69 and smaller peak at m/z 99.

Compound A, C8H10O, has the IR and 1H NMR spectra shown. Propose a structure consistent with the observed spectra, and label each peak in the NMR spectrum. Note that the absorption at 5.5 î disappears when D2O is added.
Treatment of butan-2-one (CH3COCH2CH3) with strong base followed by CH3I forms a compound Q, which gives a molecular ion in its mass spectrum at 86. The IR (> 1500 cm−1 only) and 1H NMR spectrum of Q are given below. What is the structure of Q?
