Answer 1

Answer:

Co-ordinate covalent bond is a special type of covalent bond and in which the shared pair of electrons are contributed by only one of the bonded atoms. This bond is represented by an arrow mark ("→"), pointing towards the acceptor atom. The atom which contributes electron pair for sharing is called donor atom and the atom which accepts the electron pair is called acceptor.

In order to form a co-ordinate bond between two atoms, one of the atoms should possess lone pair of electrons and the other atom should possess empty orbital .

Example

Formation of Ammonium ion (ZH+4) :

Ammonium ion is formed by the union NH3 molecule with H+ ion.

In NH3 molecule the central 'N' atom has one lone pair of electrons and H+ ion has empty orbital.

Hence, N- atom of NH3 molecule donates its lone pair to the empty orbital of H+ ion, forming a co-ordinate covalent bond between them.

Answer 2

Explanation:

A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. ... In the formation of a simple covalent bond, each atom supplies one electron to the bond - but that does not have to be the case....

Examples are- An example of a coordinate bond is the relationship between hydrogen chloride and ammonia when the ammonium ions are formed by the transfer of a hydrogen ion to the pair of electrons in the ammonia molecule..
