Correct answer

D. Cannizzaro's reaction

Step-by-step solution

Benzaldehyde ( C₆H₅CHO ) is an aldehyde that does not contain any -hydrogen atom. When treated with a concentrated alkali solution, it undergoes a disproportionation reaction (self-oxidation and self-reduction) to form one molecule of benzyl alcohol ( C₆H₅CH₂OH ) and one molecule of a salt of benzoic acid ( C₆H₅COO^- ). This reaction is known as Cannizzaro's reaction. 2C₆H₅CHO + NaOH C₆H₅CH₂OH + C₆H₅COONa Wurtz, Fittig, and Wurtz-Fittig reactions are coupling reactions involving alkyl and/or aryl halides in the pre
