why does ammonium hydroxide react with Acetone and does NOT react with Acetaldehyde?

Question

This experemet called Iodoform Test for identification of carbonyl group.
Please when you answer my question tell me your Referance (Source) it is very important

Answer 1

Both acetone & acetaldehyde test positive in the iodoform
reaction. Acetaldehyde is the only aldehyde to test positive
in this reaction which detects the presence of methyl ketones
or alcohols possessing the feature CH3(CH)OH-R.

I would suggest that the reason ammonium hydroxide reacts with acetone but not acetaldehyde is not down to the carbonyl
[C = O] group which both possess but rather the ammonia component of ammonium hydroxide which splits to form ammonia & hydroxide. Disregard the hydroxide component
in your thinking, I suggest!

Answer 2

Too lazy to do your own research?
