Question

Which of the following ketones will give a positive iodoform test? OH Banco con el cos arbat-en a time -CH3 CH-C-CH-CH3 -CH-CH: (A) I and II OH O o III ch-E-CH,-CH:CH-CH,––CH,CH; (C) III and a IV V OA. OB. OC. OD.

Answer 1

I think the structure of II part is incorrect because the C having OH does not have four bonds so it should be like CH3-CH-OH....if it is so then this will show iodoform test because CH3CH(OH) group gives positive test for iodoform.

Godofoum test is given by most of the compound which have a - R-C-CH3 group the mythey should lee directly attached to the colobon containing the functional gucoup o 1 x iodoform because &-CH₂-CH₂ X because its an alcohol U v because it has CH₂ - Č Ñ X no C CH3 T X no Eche

So the answer in that case will be II and III will show the test
