AIIMS 2014 Chemistry Aldehyde reactions MCQ Question

The compound C3H6O is likely a ketone, as it does not react with Tollen's reagent (which indicates the absence of an aldehyde) but does form an oxime with hydroxylamine, suggesting the presence of a carbonyl group. Ketones can give a positive iodoform test if they have a methyl group adjacent to the carbonyl, which is the case for some ketones, making option A the correct answer. In contrast, the other tests mentioned (Fehling's, Schiff's, and carbylamines) are primarily used for aldehydes or specific amines, not ketones.
