Vedclass · Answer

(D) In the structure of ice, each oxygen atom is tetrahedrally surrounded by four other oxygen atoms at a distance of $276 \ pm$. These oxygen atoms are linked by hydrogen bonds. Each oxygen atom is covalently bonded to two hydrogen atoms and hydrogen-bonded to two other hydrogen atoms from neighboring water molecules. Therefore, each oxygen atom is surrounded by two hydrogen atoms via covalent bonds and two hydrogen atoms via hydrogen bonds, totaling four hydrogen atoms. Option $D$ is incorrect because each oxygen atom is surrounded by two covalent bonds and two hydrogen bonds, not four hydrogen bonds.
