Question

In open cage-like structure of ice, bonds present are:

• A. covalent and hydrogen bonds
• B. covalent and co-ordinate bonds
• C. co-ordinate and H-bonds
• D. hydrogen bonds only

Answer 1

The correct option is A covalent and hydrogen bonds

In ice, four hydrogen atoms tetrahedrally surround each oxygen atom in such a way that two hydrogen atoms are linked to oxygen atom by covalent bonds (These lie closer to the oxygen atom at a distance of $1.00\AA$) and the other two hydrogen atoms are linked to the central oxygen atom by hydrogen bonds. (These lie away from oxygen atom at a distance of $1.76\AA .$) The hydrogen atoms of water molecules are located at the corners of tetrahedron.
