Problem

Compounds A and B are alcohols with the molecular formula

C_3H_8O

. The following information was obtained from a mass spectrum of each alcohol. A: peaks at

m/z = 29, 31, 60

B: peaks at

m/z = 45, 60

(a) Deduce the formula of the species responsible for the peak at

m/z = 60

. (b) Deduce the formula of the species with

m/z = 31

. (c) Deduce the structure of each alcohol.
