The detailed mechanism for the formation of fluorenone from fluorene should be written. Also, the purpose of the phase −transfer-catalyst should be explained. Concept introduction: The phase-transfer-catalyst is a catalyst that helps in the migration of the reactant molecules from one phase to another. It is a special kind of heterogeneous catalyst. Phase-transfer-catalyst is used in green chemistry, asymmetric alkylations, and in the preparation of polyester polymers. Crown ethers, ammonium, and phosphonium salts are some examples of phase-transfer-catalysts.

2. Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated. OH CH-COOH 0 HO CN C H30* C. H H HC N NaOH H₂O C=O 0 cyanohydrin H + NaCN + H₂O
