Use the following information to propose a molecular formula for nootkatone, a compound partly responsible for the characteristic odor of grapefruit. Nootkatone contains the elements C, H, and O, has ve degrees of unsaturation, and a molecular ion in its mass spectrum at m/z = 218.
A compound containing only carbon, nitrogen, oxygen, and hydrogen contains four carbon atoms. If the M+ peak in its mass spectrum appears at m/z = 87, then how many nitrogen atoms does it contain?
The molecular ion peak in a mass spectrum of compound W appears at m/z = 107. Predict the molecular
formula of compound W. (Hint: Compound W contains a heteroatom, not only carbon and hydrogen).
