CO
Total Number of Valence Electron: 4
Bond Structure: Carbon monoxide consists of one carbon atom and one oxygen atom, connected by a triple bond that consists of a net two pi bonds and one sigma bond.
Bond Order: 3
Bond Length: 112.8 pm
HCN
Total number of Valence Electron: 10
Bond Structure: Hydrogen Cyanide is a highly toxic conjugate acid of a cyanide that is used as a chemical weapon agent.
Bond Order: 3
Bond Length:
CS2
Total number of valence electron: 16
Bond Structure: Carbon disulfide appears as a clear colorless to light yellow volatile liquid with a strong disagreeable odor.
Bond Order:
Bond Length:
CH4
Total number of valence electron: 8
Bond Structure: Methane (US: /ˈmɛθeɪn/ or UK: /ˈmiːθeɪn/) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas.
Bond Order: Methane has four σ MOs and four σ* MOs. All of the electrons are in the bonding orbitals. The bond order in methane is then = 0.5(8-0) = 4. This is not because there is a quadruple bond.
Bond Length: The C-C bond length is 1.54 Å. As in methane, the C-H bond length is 1.09 Å,and the bond angles are 109°28'.
CaC2
Total number of valence electron: Around each carbon atom there are 5 valence electrons: 3 from the double bond, and 2 in a lone pair. Given the 2 inner shell electrons, this gives 7 electrons per carbon nucleus.
Bond Structure: Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2.
Bond Order: 3
Bond Length: C triple bond length is about 1.092 Å (similar to ethyne).
That's all I know. Correct me if I'm wrong.
