8.27 Hydrocarbon A has the formula CH and absorbs 3 equivalents of H to yield B CH when hydrogenated over a Pd/C catalyst. On treatment of A with aqueous HSO in the presence of mercury (ll), two isomeric ketones, C and D, are produced. Oxidation of A with KMnO gives a mixture of acetic acid (CHCOH) and the tricarboxylic acid E propose structures for compounds A-D, and writ the reactions
8.28 How would you carry out following reaclions?
8.29 Occasionally, chemists need to invert the stereochemistry of an alkene- that is, to convert a cis alkene to a trans alkene , or vice versa. There is no one-step method for doing an alkene inversion, but the transformation can be carried out by combining several reactions in the proper sequence. How would you carry out the following reactions?
8.30 Propose structures for hydrocarbons that give the following products on oxidative cleavage by KMnO or O
8.30 Each of the following syntheses requires more than one step. How would you carry them out?
8.31 Each of the following syntheses requies more than one step. How would you carry them out?
8.32 How would you carry out the following transformation? More than one step is needed.
8.33 How would you carry out the following conversions? More than one step is needed.
8.34 Synthesize the following compounds using 1-butyne as the only source of carbon along with any inorganic reagents you need more than one step may be needed
