Types of chemical bonds.
Chemical bond :- a bond between two atoms is formed when there is sharing of electrons or gain/loss to form a stable compounds.
Type of chemical bonds :
1) covalent bond : it is formed when there is sharing of electrons between two atoms. Also known as π-π bond . ( Lateral overlap)
E.g -CH4 , CO.
2) coordinate- covalent bond : It is formed when there is sharing of lone pair of electrons between non-metal to metal.
E.g-. Comples
3) ionic bond : it is formed by gain or loss of electrons between two atoms . Also known as sigam bond ( axial overlap).
E.g -. NaCl.
4) Hydrogen bonds : it is formed due to polarity between two atoms . It is weak bond . It is formed between hydrogen & electronagative atom of another compound.
a) intermolecular hydrogen bonding : it is weak bond formed between hydrogen & electronegative atom of another compound.
e.g. H2O,NH3.
b) intermolecular hydrogen bonding: it is formed within same molecule between hydrogen & electronegative atom.
e.g CHCl3 , NH3.
