Account for the peaks at m>z 87, 111, and 126 in the mass spectrum of 2,6-dimethylheptan-4-ol.

Problem-solving Hint In general, you should be able to propose favorable fragmentations for two or three of the largest peaks in a spectrum. Also, the spectrum should contain large peaks corresponding to the most favorable fragmentations of your proposed structure. You shouldn’t expect to account for all the peaks, however.
