Which of the following reaction will not result in the formation of carbon-carbon bonds? (CBSE AIPMT 2010)

Cannizzaro’s reaction is a chemical property of the aldehydes. The aldehydes that do not have 훼− 퐻푦푑푟표푔푒푛 can undergo disproportionation reaction, i.e., self oxidation and reduction reaction. So by oxidation, sodium salts of carboxylic acid are formed and by reduction, alcohols are formed. So, the products formed Aldehydes and Ketones 31 by the Cannizaro’s reaction does not involve carbon- carbon bond.
