Explain the formation of coordinate covalent bond with one example
Answers
Explanation:
lone pair of one atom share by both
❤. Co-ordinate covalent bond is a special type of covalent bond.
❤. In this type , two atoms share one pair of electrons, but the shared pair is contributed by only one of atoms.
❤. The atom which contributes the electron pair for sharing is called donor atom, while the other atom is called acceptor atom.
❤. The donor atom must be having one or two lone pairs of electrons.
❤. While the acceptor atom is short of two electrons to get its octet.
❤. The Co-ordinate bond is represented by an arrow mark from donor to acceptor (A-->B)
⭐⭐⭐⭐FORMATION OF AMMONIUM ION (NH+4) ⭐⭐⭐⭐
❤. Ammonium ion is formed by the union of NH3 molecule with H+ ion.
❤. In NH3 molecule the central 'N' atom has one lone pair of electron and H+ ion has empty orbital.
❤. Hence, N atom of NH3 molecule donates its lone pair to the empty orbital of H+ ion.
❤. Thus a co-ordinatw covalent bomd is formed between N and H+.
