Question

carbon is the only element that forms long chains, making it fundamental to organic molecules. true false

Explanation:

Carbon can form long chains (catenation) due to its ability to form stable covalent bonds with itself. This property is crucial for organic molecules (like hydrocarbons, polymers etc.). While other elements like silicon can also show some catenation, carbon's catenation ability is far more extensive and important for the vast diversity of organic compounds.
