What is a co-ordinate bond? Give one example.
Original Khojo Papers practice question — not from a past board paper.
Answer
A co-ordinate or dative bond is a covalent bond in which both the shared electrons are supplied by one of the two atoms. It is found in the ammonium ion, where the nitrogen atom of ammonia donates its lone pair to a hydrogen ion.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Once formed, a co-ordinate bond is identical to any other covalent bond; only its origin is different.
