Ketones and Aldehydes
R C H R C R aldehyde ketone An aldehyde has one alkyl (or aryl) group and one hydrogen bonded to the carbonyl carbon Structure of the carbonyl group The carbonyl carbon is sp2 hybridized and has a partially filled unhybridized p orbital perpendicular to the framework |
Are aldehydes and ketones nucleophilic?
In addition to nucleophilic additions, aldehydes and ketones show an unusual acidity of hydrogen atoms attached to carbons alpha (adjacent) to the carbonyl group. These hydrogens are referred to as α hydrogens, and the carbon to which they are bonded is an α carbon.
How do you convert acid halides to ketones?
Acid halides can be converted to ketones by reacting with Gilman reagents. Aldehydes can be oxidized more easily than ketones due to the aldehyde hydrogen. Jones reagent is a mixture of CrO 3 and aqueous acid. Aldehydes can be oxidized to carboxylic acids with chromium trioxide/Jones reagent.
Can aldehydes be oxidized to carboxylic acids?
Aldehydes can be oxidized to carboxylic acids with chromium trioxide/Jones reagent. Ketones can undergo oxidative cleavage with very strong oxidizing agents such as potassium permanganate. Ketones can be oxidized to esters by peroxycarboxylic acids in a reaction known as Baeyer-Villiger oxidation.
What is the reaction between aldehydes and ketones?
The most common reaction of aldehydes and ketones is nucleophilic addition. This is usually the addition of a nucleophile and a proton across the C=O double bond. As the nucleophile attacks the carbonyl group, the carbon atom changes from sp2 to sp3. The electrons of the bond are pushed out onto the oxygen, generating an alkoxide anion.
