Advertisements
उत्तर
- The unique property of carbon atom to form covalent bonds with other carbon atoms giving rise to extremely big molecules is called catenation power.
- The covalent bond between two carbon atoms is strong and stable.
- This is the reason carbon is bestowed with catenation power.
- Due to catenation power, carbon can form a large number of compounds containing open chains or closed chains of carbon atoms.
