WebDec 20, 2024 · The carbonyl ligand (CO) distinguishes itself from other ligands in many respects. For example, unlike the alkyl ligands, the carbonyl (CO) ligand is unsaturated thus allowing not only the ligand to σ−donate but also to accept electrons in its π* orbital from dπ metal orbitals and thereby making the CO ligand π−acidic. Webcarbonyl: [noun] an organic functional group or radical −CO− occurring in aldehydes, ketones, carboxylic acids, esters, and their derivatives. WebMay 11, 2024 · A carbonyl group in chemistry is a group of atoms that consists of a carbon (C) atom covalently attached to an oxygen (O) atom by a double bond: C = O. The carbon atom, to satisfy its valence of 4, must also be attached by covalent bonds to two other atoms. The simplest type of molecule that contains a carbonyl group is a ketone. mary carlyle obituary 2021
