Write a note on the anomalous behaviour of carbon in the group-14.

Explanation

Carbon shoes anamalous behavior in group -14 elements .The following facts support that anamalous behavior.
`to` Execpt carbon all other elements of group -14 has availabled orbitals and can expand octet in valency shell.
`to` Carbon occurs in free state but not the other elements of this group .
`to` Maxium covalenecy of carbon in four but for silicon is six.
`to` Carbon can form multiple bond with C,O,S,etc .
`to` Hydrocarbons are more stable thermally than silanes.
