Hydrocarbon A (C 9 H 12 ) absorbs 3 equivalents of H 2 in the presence of Pd/C to yield B (C 9 H 18 ). A when treated with aqueous H 2 SO 4 in the presence of Hg(II) gives two isomeric ketones C and D . A upon oxidation with KMnO 4 gives a mixture of acetic acid and tricarboxylic acid E . Based on these data, structures for the compounds A - D are to be given and the reactions are to be written. Concept introduction: The degree of unsaturation can be calculated by comparing the molecular formula of compound given with that of its parent hydrocarbon. Both alkenes and alkynes yield alkanes by adsorbing H 2 in the presence of Pd catalyst. Alkynes require two equivalents of H 2 while alkenes require one equivalent of H 2 to give alkanes. Internal alkynes will yield a mixture of isomeric ketones when treated with aqueous H 2 SO 4 in the presence of mercury (II) if they are symmetrically substituted. When oxidized with KMnO 4 , monosubstituted carbons in both double and triple bonds get oxidized to carboxylic acids. To give: Based on the data given, the structures of A - D and to write the reactions.

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
