Question

(CCHBrCH (E) CH,O-- CHB.CH 18) The reduction of cyclohexanone in isopropyl alcohol in the presence of aluminum isopropoxide can be used to prepare cyclohexanol in a good yield only if which of the following conditions is fulfilled? (A) The reaction is carried out at 0° C (B) The reaction is irradiated with sunlight. (C) The acetone formed in the reaction is distilled away as the reaction is taking place. D) The cyclohexanol is distilled away from the reaction mixture as the reaction is taking place. (E) The reaction is catalyzed with mercuric chioride.

Answer 1

Acteone is the side product of this reduction reaction. So it has to be removed from reaction mixture otherwise it will also undergo reduction process, in presence of the catalyst aluminiumisopropoxide. The catalyst will get engaged for this and main reaction will get down.
