What is meant by catenation, and which element shows it to the greatest extent?
Original Khojo Papers practice question — not from a past board paper.
Answer
Catenation is the ability of an element's atoms to link with one another to form long chains, branched chains and rings. Carbon shows it to the greatest extent because the carbon–carbon bond is exceptionally strong.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Silicon catenates too, but its chains are short because the Si–Si bond is much weaker.
