Sum of oxidation state of nitrogen atom in hyponitrous acid, nitric acid and nitrous acid. — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Graphite has a layered structure where carbon atoms within each layer are strongly held together by covalent bonds in hexagonal sheets. Step 2: These individual parallel layers are held together by very weak intermolecular van der Waals forces. Step 3: The weakness of these forces allows the layers to easily slide over one another under slight mechanical force, giving graphite its lubricating and slippery properties. This matches option (c).
