Answer
The bond formed between two atoms by sharing a pair of electrons, provided entirely by one of the combining atoms but shared by both is called a coordinate bond.
Conditions for the formation of coordinate bond are:
(i) One of the two atoms must have at least one lone pair of electrons, e.g., ammonia (NH3), water (H2O).
(ii) Another atom should be short of at least a pair of electrons, e.g., Hydrogen ion (H+).
