Hydrocarbon A has the formula C9H12 and absorbs 8 equivalents of
H2
to yield B, C9H18, when hydrogenated over a Pd/C catalyst. On
treatment
of A with aqueous H2SO4 in the presence of mercury(II), two
isomeric
ketones, C and D, are produced. Oxidation of A with KMnO4
gives a mixture of acetic acid (CH3CO2H) and the tricarboxylic
acid E.
