In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acid ), as part of many larger functional groups.

Jan 23, 2023 · A carbonyl group is a chemically organic functional group composed of a carbon atom double-bonded to an oxygen atom --> [C=O] The simplest carbonyl groups are aldehydes and ketones usually …

Carbonyl group, in organic chemistry, a divalent chemical unit consisting of a carbon (C) and an oxygen (O) atom connected by a double bond. The group is a constituent of carboxylic acids, esters, anhydrides, acyl halides, amides, and quinones, and …

A carbonyl group is a functional group featuring a double bond between a carbon atom and an oxygen atom (illustrated below). However, the term ‘Carbonyl’ can also refer to carbon monoxide as the ligand within an organometallic or inorganic compound (say a metal carbonyl, such as nickel carbonyl).

Jun 19, 2019 · A carbonyl group is a functional group in biochemistry characterized by a carbon atom double bonded to an oxygen, with a larger molecule. This structure creates a resonance hybrid structure within the molecule, in which the electrons are continuously redistributed between the carbons and the oxygen, which can allow the molecule to hold more ...

Jan 18, 2025 · The carbonyl group, defined by a carbon atom double-bonded to an oxygen atom, is a key feature in organic chemistry. This double bond involves a complex interplay of atomic orbitals, giving rise to the carbonyl’s distinctive properties.

Mar 26, 2025 · A carbonyl group consists of a carbon atom double-bonded to an oxygen atom (C=O). The carbon is sp² hybridized, giving the group a planar geometry. The carbon atom in the carbonyl group is electrophilic (electron-deficient), while the oxygen is nucleophilic (electron-rich) due to its higher electronegativity.

The carbonyl group is ubiquitous in biological compounds. It is found in carbohydrates, fats, proteins, nucleic acids, hormones, and vitamins—organic compounds critical to living systems. In an aldehyde, at least one of the attached groups must be a hydrogen atom.

Jan 12, 2025 · The carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom. It is commonly found in aldehydes and ketones. The carbonyl group is a crucial structural element in organic chemistry, influencing the reactivity and properties of molecules it is part of.

Before we introduce them, we define the carbonyl group, which is formed when an O atom and a C atom are joined by a double bond: The other two bonds on the C atom are attached to other atoms. It is the identities of these other atoms that define what specific type of compound an organic molecule is.
