For example, with propanone you get propan-2-ol: Reduction of a ketone leads to a secondary alcohol. A secondary alcohol is one which has two alkyl groups attached to the carbon with the -OH group on it.

Due to different active groups, aldehyde and ketone indicate different reactions for same reagent. But sometimes they show same changes (like colour changes) to some reagents.

For example, the Robinson annulation reaction sequence features an aldol condensation; the Wieland–Miescher ketone product is an important starting material for many organic syntheses. Aldehyde & Ketone Aldehydes, and ketones are important carbonyl compounds (a compound that bears a C=O group) for organic synthesis because they can readily be oxidized, or reduced into other chemical materials. One way you could do it is using trifluoroperoxyacetic acid (a Baeyer-Villiger oxidation), and then using diisobutylaluminium hydride (DIBAH) in Toluene in the presence of a dry ice bath. I'm unsure as to how these react in more complicated contexts, but let's take acetone and convert it to acetaldehyde: Neither mechanism is particularly well-known, but in general, in step 1, an oxygen is The difference between ketone and aldehyde is the carbonyl group present in aldehydes can be easily oxidised to carboxylic acids whereas the carbonyl group in ketones are not oxidised easily. This difference in reactivity is the basis for the distinction of aldehydes and ketones.

Aldehydes and ketones are organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen. Aldehydes and Ketones are often called as methanoyl or formyl group. The carbon atom of this group has 2 remaining bonds that might be occupied by aryl or alkyl or substituents. If neither of these substituents is hydrogen, the compound is a Ketone.

Oxidation of Primary, Secondary, Tertiary Alcohols to Aldehyde, Ketone, Carboxylic Acid. Oxidation of primary, secondary, tertiary alcohols will give aldehyde, ketone and carboxylic acid as products. For oxidation, several oxidizing agents are used. According to the alcohol type, given product will vary.
