carbonyl
adj 1: relating to or containing the carbonyl group [synonym:
{carbonyl}, {carbonylic}]
n 1: a compound containing metal combined with carbon monoxide

Oxalyl \Ox"a*lyl\, n. [Oxalic -yl.] (Chem.)
(a) A hydrocarbon radical ({C2O2}) regarded as a residue of
oxalic acid and occurring in derivatives of it.
(b) An old name for {carbonyl}.
(c) An old name for {carboxyl}.
[1913 Webster]


Carbonyl \Car"bon*yl\, n. [Carbon -yl.] (Chem.)
The radical ({=CO}), occuring, always combined, in many
compounds, as the aldehydes, the ketones, urea, carbonyl
chloride, etc.
[1913 Webster]

Note: Though denoted by a formula identical with that of
carbon monoxide, it is chemically distinct, as carbon
seems to be divalent in carbon monoxide, but
tetravalent in carbonyl compounds.
[1913 Webster]

{Carbonyl chloride} (Chem.), a colorless gas, {COCl2}, of
offensive odor, and easily condensable to liquid. It is
formed from chlorine and carbon monoxide, under the
influence of light, and hence has been called {phosgene},
or {phosgene gas}; -- called also {carbon oxychloride}. It
is used in chemical synthesis, and was also used as a
poison gas in World War I.
[1913 Webster PJC]

    As a result, the carbonyl group is best described as a hybrid of the following resonance structures We can represent the polar nature of this hybrid by indicating the presence of a slight negative charge on the oxygen (d -) and a slight positive charge (d +) on the carbon of the C=O double bond
