6. Which of the following molecules cannot undergo oxidation? i. 2-methyl-2-propanol ii. 1-propanol iii. 2-propanol Tertiary alcohols (R3COH) 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. Therefore, 2 - methyl - 2-propanol is tertiary alcohol so it cannot oxidize due to the...
