Question

Define what a bond formed by the shared pair of electrons with both electrons coming from the same atom is called ……..... .

Answer 1

Hint: Each atom supplies one electron to the bond in the formation of simple covalent bond and the coordination bond (also called dative covalent bond) is the type of covalent bond which is formed by the shared pair of electrons and both electrons comes from the same atom.

Complete answer: First we will discuss about the chemical bonding,
Chemical bond is defined as the attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond is formed by the electrostatic forces of attraction between oppositely charged ions as in ionic bonds (like the bond formed between the positive ions and negative ions) or through the sharing of electrons as covalent bonds.
Now we will discuss about the statement which is given in the question,
The bond formed by the shared pair of electrons with both electrons coming from the same atom is called coordination bond.
So according to the question,
Coordination bond is called the coordination covalent bond or dative bond or dipolar bond. The dative bond is indicated by drawing an arrow pointing from the atom that donated the lone pair of electrons toward the atom that accepts the pair. The atoms are held together because the electron pair is attracted by both nuclei. The kind of interaction present between the metal ions and legends is coordinating interaction. For example: - the relationship between hydrogen chloride and ammonia when ammonium ions are formed by the transfer of hydrogen ions to the pair of electrons in the ammonium molecules.
So the correct statement is,
Coordination bond is formed by the shared pair of electrons with both electrons coming from the same atom.

Note: Dative bond or coordination bond or dipolar bond are common when metal ions bind to ligands. The bonding between water and metal cation is an example of coordination bond and even in metal-ligands interaction most organ metallic compounds and coordination compounds are explained similarly.
