Struktura molekuly oxidu uhelnatého
Na wikipedii je struktura molekuly CO s trojnou vazbou a jedním elektronovým párem na uhlíku a kyslíku. Není to špatně. Vazba by měla být dvojná a jeden elektronový pár na uhlíku a dva na kyslíku. Jinak mi to nesedí ani když si rozkreslím elektronové orbitaly. (alespoň nás to tak učili na VŠ)?

Angl. wiki k tomu má povídání:
"The carbon and oxygen are connected by a triple bond that consists of a net two pi bonds and one sigma bond. The bond length between the carbon atom and the oxygen atom is 112.8 pm. Carbon–oxygen double bonds are significantly longer, 120.8 pm. The ground electronic state of carbon monoxide is a singlet state since there are no unpaired electrons.
Carbon and oxygen together have a total of 10 electrons in the valence shell. Following the octet rule for both carbon and oxygen, the two atoms form a triple bond, with six shared electrons in three bonding molecular orbitals, rather than the usual double bond found in organic carbonyl compounds. Since four of the shared electrons come from the oxygen atom and only two from carbon, one bonding orbital is occupied by two electrons from oxygen, forming a dative or dipolar bond."
