What is a coordinate covalent bond?
Quick Answer
A coordinate covalent bond is a covalent bond in which both shared electrons come from the same atom. It is also called a dative bond.
The Full Story
This type of bond forms when one atom with a lone pair donates both electrons to an atom or ion that needs them. Once formed, it behaves like any other covalent bond. A common example is the bond between ammonia and a proton to form the ammonium ion, NH4+. Coordinate covalent bonding is important in coordination chemistry and many biological and industrial processes.
Key Facts
1.Both electrons in the bond come from one atom
