Class 10 Co-ordinate covalent bond - Dative bond - ICSE

 Co-ordinate covalent bond - Dative bond - ICSE

Co-ordinate covalent bond (or) Dative bond:

The bond formed by the sharing of electron pair between two atoms where one atom contributes both the electron.

 

Example 1  : Formation of Hydronium ion [H₃O⁺]:

 

    the co-ordinate covalent bond between Oxygen atom and Hydrogen where both the electrons coming from Oxygen atom but being shared by Oxygen and Hydrogen. This is due to the lone pair effect of Oxygen atom in water molecule.

Hydromium ion : 1-dative bond and 2 covalent bonds.

 

Example 2: Formation of Ammonium ion [NH₄⁺]:

Ammonium ion : 1- dative bond and 3- covalent bonds.
