Reactivity increases in the order:
Explanation:
Consider the organic shrubbery substituting the carbonyl group. Phenylacetone has a whopping great phenyl group; acetone has 2 methyl groups, versus acetaldehyde, 1 methyl, and 1 hydrogen.
Now it is well-known that aldehydes are much more reactive than ketones, so acetaldehyde is the MOST reactive. Next comes the ketone, acetone, and least reactive to substitution is the phenylacetone.
