need help on all of these. Any help is much appreciated!

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 the only product of oxidative cleavage with O3 followed by CH:SCH3. Give the structures of A. 6) Compound B has the molecular formula of C6H1o and gives (CH3)2CHCH2CH2CH3 when treated with excess H2 in the presence of Pd. B reacts with NaNH2 and CH3I to form compound C that has the molecular formula C H12. Give structures for B and C. 6. Dihydroxylation of an alkene can be carried out with H2O2 in HCO2H. In this reaction, trans- 2-butene gives (2R,3S)-butane-2,3-diol, whereas cis-2-butene gives a mixture of (2R 3R) and (2S,3S)-butane-2,3-diol. Does dihydroxylation by the method occur with syn or anti addition?
