POINTS TO REMEMBER

Bonding In Carbon – The Covalent Bond

Covalent bond is formed by mutual sharing of electrons between the two atoms so that each of the atoms attains noble gas configuration.

■ Covalent bond can be single, double or triple bond depending upon the number of shared pairs of electrons between them.

■ Carbon shares its valence electrons with atoms of various elements to form a variety of compounds.

■ Carbon can form single, double and triple covalent bonds with itself as well as with other atoms.

■ Covalent compounds generally have low melting and boiling points, low solubility in water and are non-conductors of electricity.
