Aldehydes vs Ketones: What’s The Difference?

WebAs text, an aldehyde group is represented as –CHO; a ketone is represented as –C(O)– or –CO–. In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibits sp 2 hybridization. Two of the sp 2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the … WebAldehydes and Ketones. Both aldehydes and ketones contain a carbonyl group, a functional group with a carbon-oxygen double bond. The names for aldehyde and ketone compounds are derived using similar nomenclature rules as for alkanes and alcohols, and include the class-identifying suffixes -al and -one, respectively:

WebThese conjugated carbonyl are called enones or α, β unsaturated carbonyls. A resonance description of this transmission is shown below. From this formula it should be clear that nucleophiles may attack either at the carbonyl carbon, as for any aldehyde, ketone or carboxylic acid derivative, or at the beta-carbon. WebAldehydes and ketones are simple compounds which contain a carbonyl group - a carbon-oxygen double bond. They are simple in the sense that they don't have other reactive …

WebVideo transcript. Voiceover: We've seen a lot of nucleophilic addition reactions to aldehydes and ketones and in this video we're going to look at the addition of carbon nucleophiles. If I started with an aldehyde or ketone and I add something like potassium cyanide and a source of protons, I'm going to form a cyanohydrate over here.
