Why Oxygen form Coordinate bond instead of Covalent bond with Nitrogen, Sulphur, etc. In N2O, SO4-²
Co-ordinate bond is type of bond which is formed between two atoms in which one atom completely donates its two electron or one lone pair to second atom. What we usually see in covalent bond is that in covalent bond 1 electron is shared by one atom and the another electron is shared by II atom, so in covalent bond there is sharing of electrons. But in co-ordinate bond, the two electrons come from single atom which is called donor atom(as it donates its lone pair) and the atom to which lone pairs are donated , or we can say the atom which is receiving electrons or lone pair is known as receiver atom. Now the question arises that oxygen has 6 electrons and if it gets two more electrons, then its octet will be completed and it will become stable. During the formation of a co-ordinate bond the donor atom donates two electrons which suggests that the donor atom has two free electrons which are not involved with any other atom in bond i.e., they are just free to use. So why ...
