Dehydrated flavoring constituents

Professor Rufus T. Firefly of Fredonia State University wanted to stump his ace chemistry student. Sea Water (C-H2O, alias formaldehyde). The professor asked Sea Water to deduce the structure of menthol, the principal flavoring constituent of peppermint, on the basis of the following data the molecular formula of menthol is C10H20O when heated in the presence of sulfuric acid, a dehydration reaction ensues to form compound A ozonolysis of compound A followed by a reductive workup yields 3,7-dimethyl-6-oxo-octanal menthol also reacts with nitric acid and vanadium oxide, when heated, to form 2-isopropyl-5-methyl-hexanedioic acid.
