#Cannizzaro reaction

Physical Properties and Nucleophilic Addition Reactions

What is the product when 2-methylpropanal undergoes Cannizzaro reaction?

2-Methylpropanal ((CH₃)₂CHCHO) has no α-hydrogens, so it undergoes Cannizzaro reaction, forming 2-methylpropanol ((CH₃)₂CHCH₂OH) and 2-methylpropanoate.
