Which element forms the backbone of all organic compounds due to its unique tetravalency and strong catenation property?

💡 Solution & Explanation

Carbon forms the backbone of all organic compounds due to its tetravalent nature and exceptional catenation property, allowing it to form stable single, double, and triple covalent bonds with itself and other elements. Other group elements like silicon exhibit weaker catenation due to larger atomic sizes and lower bond dissociation energies.
