A substance that gives positive iodoform test will most probably not give which reaction

Explanation

Idoform test needs α - H.The Cannizzaro reaction is a disproportionation reaction that occurs in aldehydes with no alpha hydrogens. In this reaction, one molecule of the aldehyde is reduced to an alcohol, while another molecule is oxidized to a carboxylic acid. However, for a substance to give a positive iodoform test, it needs to have a methyl ketone functional group (CH3-CO-). This means it must have at least one alpha hydrogen atom attached to the carbonyl carbon. Since the Cannizzaro reaction requires aldehydes without alpha hydrogens, a substance that gives a positive iodoform test will most probably not undergo the Cannizzaro reaction.
