Question

Define a coordinate bond and give the conditions for its
formation.
​

Answer 1

Coordinate bond is formed when the shared pair of electrons is provided by one of the two atoms and it is shared by both the atoms. The conditions necessary for the formation of coordinate bond are:

(1). One of the atoms should have a lone pair of electron to share which is known as donor atom.

(2). The other atom must have an incomplete outermost shell which shares the electron pair is known as the acceptor atom.

Answer 2

Answer:

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. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
