MCQ
What is the mechanism of the Cannizzaro reaction?
Chemistry
A Nucleophilic addition to carbonyl
B Disproportionation of an aldehyde without alpha-hydrogens
C Radical chain reaction
D Electrophilic aromatic substitution
Explanation

In the Cannizzaro reaction, an aldehyde lacking alpha-hydrogens (like benzaldehyde) undergoes base-induced disproportionation to form an alcohol and a carboxylate salt.
