Sodium bicarbonate has: — s Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Analyze the bonding in sodium bicarbonate (NaHCO3). It is an ionic salt composed of Na+ cations and HCO3- anions, forming ionic bonds. Step 2: Within the polyatomic bicarbonate anion, the carbon, oxygen, and hydrogen atoms are linked via covalent bonds. Furthermore, in the solid crystal lattice, bicarbonate units form polymeric structures held together by intermolecular O-H...O hydrogen bonds. Step 3: Therefore, all three types of bonds (ionic, covalent, and hydrogen bonds) are present, which corresponds to option (d).
