Read the passage given below and answer the following questions 53-55. The electrochemical reduction of benzaldehyde and p-tolualdehyde has been achieved by diphenyl ditelluride and diphenyl diselenide as catalyst using undivided cell containing graphite (cathode) and aluminium (anode) electrodes. The products of electrochemical reduction are benzyl alcohol and p-methyl benzyl alcohol. They are characterised by by melting and boiling points. The yields of alcohol depends upon the kind of dichalcogenides compounds. The reduction is carried out in atmosphere of nitrogen. p-methyl benzaldehyde on reduction gives p-methyl benzyl alcohol.
