Describe the structure of common from of ice.

Text Solution

Verified by Experts

In the normal hexagonal ice, each oxygen atom is tetrahedrally surroundanded by four other oxygen atoms, there being an hydrogen atom in between each pair of oxygen. Each hydrogen is covalent bonded to one oxygen and linked to the other oxygen by a covalent bond. Such an arrangement leads to packing having large open spaces. The density of ice is therefore less than liquid water.
