Iodoform test with ethanol
WebIodoform testing is given by those compounds with the COCH 3 group and those alcohols that produce the CH 3 CO group in oxidation. So here acetone has the COCH 3 group and ethanol in oxidation produces CH 3 CHO and hence it has the CH 3 CO group but in diethyl ketone we have CH 3 CH 2 COCH 2 CH 3 which means we have an ethyl group so Web8 apr. 2024 · The iodoform test is used to determine whether a given unknown chemical substance contains carbonyl compounds with an α-methyl group and the structural …
