Question

why dative bond is always polar?
​

Answer 1

Explanation:a dative bond is formed when an atom on one molecule with an empty orbital interacts with an atom on a different molecule that has a lone pair on it. The atom with the empty orbital has a low core charge (and a low number of valence electrons) while the atom with the extra electrons in a lone pair has a high core charge (and a high number of valence electrons). So the one with the lone pair tends to be higher in electronegativity than the one with the empty orbital. Hence, polar bond.

Answer 2

Dative bonds are always polar because:

• A dative bond is a coordinate covalent bond present between two atoms where one of the atoms provides both electrons that form the bond.
• A dative bond is always known as a dipolar bond or covalent bond.
• The dative bonds are formed when an atom with an empty orbital tends to interact with an atom on a different molecule that has a lone pair on it.
• The atoms with empty orbitals have a lower number of valance electrons while the atom with an extra electron in a lone pair has a higher number of valance electrons.
• So the one with the lone pair tends to have higher electronegativity than the one with the empty orbital. Hence, polar bond.
