What is not true about ice? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: In the hexagonal crystalline structure of ice, each oxygen atom is tetrahedrally coordinated, being covalently bonded to two hydrogen atoms and hydrogen-bonded to two other hydrogen atoms. Step 2: Therefore, each oxygen atom has exactly 2 covalent bonds and 2 hydrogen bonds (not four hydrogen bonds) around it. Step 3: This makes statement (d) incorrect, so (d) is not true about ice.
