Chapter 16 Aldehydes and Ketones
... An aldehyde cannot have the molecular formula C5H12O. C5H12 has too many H’s. Since an aldehyde has a double bond, the number of C’s and H’s resembles an alkene, not an alkane. An aldehyde with 5 C’s would have the molecular formula C5H10O. ...

Metal carbonyl
Metal carbonyls are coordination complexes of transition metals with carbon monoxide ligands. Metal carbonyls are useful in organic synthesis and as catalysts or catalyst precursors in homogeneous catalysis, such as hydroformylation and Reppe chemistry. In the Mond process, nickel carbonyl is used to produce pure nickel. In organometallic chemistry, metal carbonyls serve as precursors for the preparation of other organometalic complexes.Metal carbonyls are toxic by skin contact, inhalation or ingestion, in part because of their ability to carbonylate hemoglobin to give carboxyhemoglobin, which prevents the binding of O2.
