Unique properties of carbon
It is a characteristic property of Carbon atom by virtue of which it can form four covalent bonds.
Atomic Number =6
Valency =+4 or -4
It mainly forms covalent compounds.
“The property of forming bonds with atoms of same element and give rise to long chains, branched or un-branched chains.”
In 14th group the Carbon –Carbon bond requires bond dissociation energy equal to 335 KJ. The Sulphur –Sulphur bond requires energy in order of 220kJ.But, the maximum catenation is shown by carbon as it forms strong bond with atom of its own kind.
IMPORTANT FEATURE OF π BONDS
(pi) bonds are more reactive sites, as they are placed above and below the plane of bonding atoms. So, more exposed to attacking agent.
