Suggest a suitable oxidising agent for the given conversion.
`(CH_(3))_(2)C = CH-COCH_(3) to (CH_(3))_(2) C= CHCOOH`

Text Solution

Verified by Experts

Alkaline `KMnO_(4)`, acidified `K_(2)Cr_(2)O_(7)` or `HNO_(3)` cannot be used since all of these will cleave the molecule at the site of the double bond giving a mixture of ketones/acid. The most suitable reagent for this oxidation is NaOI `(I_(2)//NaOH)` since methyl ketones on treatment with NaOI undergo iodoform reaction to give iodoform along with the Na salt of a carboxylic acid having one carbon atom less than the starting methyl ketone.
