Haloform Reaction Mechanism With Methyl Ketones - Iodoform Test

This organic chemistry tutorial video provides the haloform reaction mechanism between a methyl ketone, Iodide, and the hydroxide ion. This video discusses the iodoform test of methyl ketones and some alcohols to produce iodoform - a solid yellow precipitate. This video discusses the alpha halogenation reaction mechanism of methyl ketones as well as the enolate ion intermediate that forms in the process.

    Are compounds that don't undergo the haloform reaction unreacted or have they been iodinated?

    In the last explanation the H Leaving should leave - ve charge which makes bond with oxygen but in O-I bond cleavage the oxygen atom is more electronegative ,so it should get the lone pair ,shouldn't it???

    Nope because the carbon attain negative charge so it create a double bond between c and o then already oxygen have 10 electrons so it gave a pair of electrons to iodine

    I'm guessing that it could, depending on the type of ether molecule you have. i.e. the ether must have a methyl group on at least one side. Someone correct if wrong please

    positive means showing yellow colour , when yellow colour show , when it forms iodoform (CHI3) if 2 alpha hydroxy presents then it will not form CHI3 .

    Will ethyl ketones and other ketones also give positive results for the test?

    if the ketone group is present on the second carbon of the chain it show positive for the test

    It should have methyl group attched at alpha position of carbonyl carbon to give positive test
