Why does carbon form a very large number of compounds?
Original Khojo Papers practice question — not from a past board paper.
Answer
Carbon has a valency of four and forms strong covalent bonds with other carbon atoms, so long chains, branched chains and rings can be built up. This property is called catenation. Carbon also forms strong bonds with hydrogen, oxygen, nitrogen and the halogens, and its compounds show isomerism, all of which multiply the number of possible compounds.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Silicon also catenates, but its bonds are much weaker, so its chains are short.
