Which class of compounds is most oxidized?

Question

Quizplus · Accepted Answer

Carboxylic acids have the highest degree of oxidation among the given choices as they have both a carbonyl group and a hydroxyl group bound to a carbon atom that has a double bond to an oxygen atom. Aldehydes and ketones have a carbonyl group but lack the hydroxyl group, while alcohols have a hydroxyl group but lack the carbonyl group. Alkanes, on the other hand, have no functional groups and are therefore the least oxidized.
