Bonds

it is a bondin in a pair of electron is given by only 1 element but note tat when the element donate lone pair both atoms say tat it iz tere

like in O₃

O<--O=O

the 2 O has donated its L.P to 1 O and it iz denoted by arrow bond

A bond formed between an ion and the atom of a polar covalent componud having lone pair of electrons such that the ion accepts lone pair is called coordinate covalent bond.

e.g.,Formation of hydronium ion-In water the O atom contains 2 lone pairs of electrons after completing its octet.The hydrogen ion accepts 1 lone air of electrons of the the oxygen atom of water mol.,leading to a co-ordinate covalent bond.

A covalent bond results from the sharing of pair of electrons b/w two atoms where eah atoms contributes one electron to the bond. It is also possible to have an electron pair bond where both electrons originate from one atom and none from the another. Such bonds are called C00RDINATE BONDS. Since in coordinate bonds, two electrons are shared by two atoms, they differ from the normal covalents bonds only in the way they r formed, and once formed that are identical to normal covalents bond.
It is represented as →
For eg, NH₄+, SO₃ , NH₃ AND BH₃, etc.

It is simply the linkage after the octet is complete .Then the co-ordiante bonds are formed

A dipolar bond[1], also known as coordinate link[2], coordinate covalent bond[3], dative bond[4], and semipolar bond, is a description of covalent bonding between two atoms in which both electrons shared in the bond come from the same atom.

The distinction from ordinary covalent bonding is artificial, but the terminology is popular in textbooks, especially those describing coordination compounds.

Once the bonds have been formed using this, its strength and description is no different from that of other polar covalent bonds.

Dipolar bond bonds occur when a Lewis base (an electron donor or giver) donates a pair of electrons to a Lewis acid (an electron acceptor) to give a so-called adduct.
The process of forming a dipolar bond is called coordination. The electron donor acquires a positive formal charge, while the electron acceptor acquires a negative formal charge.
