The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex (a metal carbonyl, e.g. nickel carbonyl). A carbonyl group characterizes the following types of compounds.
An ene-one molecule must have both an alkene (ene) and a ketone (one) functional group. The alkene functional group is characterized by a carbon-carbon double bond, while the ketone functional group consists of a carbon double-bonded to an oxygen and attached to two other carbon groups.
There is a double bond between two olefenic carbon atoms and it is the functional group of simple alkenes.
Carbonyl group
functional group
Carbonyl
The functional group of alkenes is a carbon-carbon double bond. This double bond consists of a sigma bond and a pi bond between the two carbons, which gives alkenes their characteristic reactivity.
In organic chemistry, an alpha carbon is the first carbon atom of an aliphatic chain which is attached to a functional group.
an oxygenThe central carbon atom in an amino acid is bonded to an amino functional group, a carboxyl functional group, a side chain, and hydrogen.
Phosphate group.
Formaldehyde, as its name implies, is an aldehyde. Thus, it contains a carbonyl (CHO) functional group. This group consists of a carbon atom double bonded to an oxygen atom. The carbonyl group is the only functional group contained in formaldehyde.
A functional group may react differently, but does not always do so. One of the well known examples is a hydroxyl group, which ionizes sufficiently to act as a weak acid when the hydroxyl group is bonded directly to a carbon atom that is part of an aromatic ring, but not when the hydroxyl group is attached to a carbon that is part of an aliphatic chain.
The group -CH3 is named methyl.
