प्रश्न
What is the unique property of carbon atom? How is this property helpful to us?
उत्तर
Self combination (catenation) is the most unique property of a carbon atom. This property is extremely as it gives rise to a large number of carbon compounds or organic compounds. Other atoms get attached to the long chain of carbon atoms in a number of ways to produce a large number of carbon compounds.
Notes
Tetravalency is the other property which supports this unique characteristic of carbon to produce a large number of carbon or organic compounds.
