3. The enzyme aconitase catalyzes the hydration (addition of water across the double bond) of aconitic acid to two products: citric acid and isocitric acid. Isocitric acid is optically active, citric acid is not. What are the structures of citric acid and isocitric acid? но HO Aconitic Acid 4. Compound A has the molecular formula of C:Hı2 and reacts with 2 equivalents of H2. A gives HCOCH2CH2CHO as...

Three isomers of C_8H_13CI (A, B, and C) all have the same carbon skeleton, but differ as to the position of where the chlorine is located. Isomer A reacts with t-butoxide to give an ether. Isomers B and C will also react with t-butoxide to give the same alkene D (C_8H_12). Treating D with HCI produces a compound (E) that is an isomer of A, B, and C. Give the structures for compounds A, B, C, D, and E in...

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.
Propose structures for compounds A-D, and write the
reactions.
