"WebKetones have two alkyl groups attached to the carbon-oxygen double bond. The simplest one is propanone. This time when you replace the R groups in the general formula for the alcohol produced you get a tertiary alcohol. A tertiary alcohol has three alkyl groups attached to the carbon with the -OH attached. " - Tertiary ketone

WebTertiary alcohols (R 3 COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms. The oxidation reactions we have described involve the formation of a carbon-to-oxygen double bond. WebWarm and distill with acidified pottasium dichromate. Then test with tollens reagent. The acidified pottasium dichromate will have oxidised the primary alcohol to an aldehyde, which will form a silver mirror with Tollen's reagent. The secondary alcohol will have been oxidised to a ketone, which does not react with Tollen's reagent.
