Coordinate Covalent Bond Definition , Examples ,Formation and Properties

What is Coordinate Covalent bond?

Coordinate Covalent bond is also known as Dative or Dipolar Bond.

Coordinate Covalent Bond Definition:

It is a type of covalent bond that forms when one atom donates a pair of electron to another atom .It is a kind of 2 – center s electron covalent bond in which the 2 electrons derive from the same atom.

Donor and Acceptor :

The atom which donates the lone pair of electron is called donor (Lewis base) and the atom which accepts the lone pair of electron is called the acceptor ( Lewis acid) in a coordinate covalent bond.

Difference between Donor and Acceptor:

It’s very easy to differentiate between donor and acceptor.

Remember that the donor is the electron rich specie and the acceptor is the electron deficient specie. For example NH3 and H2o are donors (electron rich) because they are stable molecules(Complete valence shell)and H+ ion and BF3 are examples of acceptors (electron deficient) because they are unstable (need electrons to complete their valence shell configuration).

Formation of a Coordinate bond:

In simple words, donation of lone pair (unshared electron pair) of electron by one atom (donor) results in the formation of coordinate (Dative) bond.

Example of Coordinate covalent bond:

Formation of NH4+ ion

Ammonia (NH3) is a stable molecule .In ammonia ,Nitrogen is a central atom having 5 electrons in its valence shell .3 electrons are shared with 3-H atoms and 1 lone pair of electron complete the valence shell configuration .Due to the presence of one lone electron pair (un shared electron pair) ,it is electron rich specie and can donate this electron pair to another atom. Therefore ammonia is a donor.

On the other hand ,when hydrogen atom loses its one valence shell electron results in H+ ion. H+ is also known as proton because it’s having only one proton and no electron or neutron.so to complete its valence shell( duplet) H+ need two electrons .Therefore H+ is an electron acceptor.

When nitrogen in ammonia donates its lone electron pair to H+ results in the formation of coordinate covalent bond and the product formed as a result of coordinate bond is ammonium ion(NH4+) and is known as adduct.

What is adduct?

The specie formed after the donation of electron pair from donor to acceptor is called adduct. NH4+ is an example of adduct.

Representation of Coordinate covalent bond(Dative / Dipolar Bond):

Coordinate covalent bond is simply represented by an arrow pointed from donor towards acceptor.

Difference between ionic ,covalent and coordinate covalent bond:

The major difference between ionic ,covalent and coordinate bond is that the ionic bond is formed by the complete transfer of electron from one atom to another atom e.g. NaCl.

Diagram of Ionic Bond:

Covalent bond is formed by the mutual sharing of electrons between the atoms e.g. H2, Cl2 ,F2 H2O,HF etc.

Whereas Coordinate covalent bond is formed by the donation of electron pair by one atom to another atom.
