Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The haloform test is a qualitative organic test. Normally, it is applied when an unknown compound is thought to contain a methylketone structure. So compounds like acetone, methyl ethyl ketone, etc. will give a positive result. When the halogen is iodine, it is called the iodoform test and can be used because iodoform, a yellow solid (CHI3) forms and is readily observed. There are two examples where a positive test is observed and the compound is not a methyl ketone. These are 1) as Kailash states, acetaldehyde and 2) ethanol, which is oxidized to acetaldehyde, first, under the conditions of the test.

The haloform reaction is the reaction of a methyl ketone with chlorine, bromine, or iodine in the presence of hydroxide ions to give a carboxylate ion and a haloform. There is one aldehyde that undergoes the haloform reaction, which is acetaldehyde.

Compounds containing acetyl group, methyl ketone, in presence of halogen (br2) and hydroxide will give halogorm reaction. Products formed will be chx3 (haloform)
