Why carbon is so special? The important factors are Carbon - carbon bonds are strong It shows valency 4, ie. It can link to four other atoms including carbon itself H-H bond is very strong, but valency is 1, so it can only link to another atom. Carbon is unique in the sense that all electronic and steric factors favor them to form large number of compounds. Carbon shows a property called catenation What is catenation?

Catenation is the ability of a chemical element to form a long chain-like structure via a series of covalent bonds. Catenation occurs most readily in carbon, which forming covalent

Unformatted text preview: bonds with other carbon atoms. Carbon is most well known for its properties of catenation, with organic chemistry essentially being the study of catenated carbon structures. Carbon has the ability to form both sigma and pi bonds to itself. This is due to an overlap between pi-electron orbitals, allowing electron density to be shared and thus stabilising the bond. Why catenation is very limited in silicon and it does not form such large number of compounds as carbon? A double bond is not twice as strong as a single bond. Why? A double bond is one sigma and one pi. Pi bond is weaker than sigma...
