Question

describe how the water molecule arragement of ice is different from that of liquid water?

Answer 1

Water, two atoms of hydrogen and one atom of oxygen, contains two O-H bonds. Oxygen atom contains 2 lone pairs of electrons. At any stage, the partial charges lead t development of polarity and thus arises Hydrogen bonding. The molecule stays as a distorted Tetrahedral because of lone pairs.

In the diagram above we can see how as Ice, a single water molecule remains surrounded by four, each bonded to the central via hydrogen bonds shown by blue lines. This structural pattern repeats itself in 3D. But as ICE turns into water, the distortion of the tight structure takes place. The hydrogen bonds break occasionally and the structure loses its lattice nature.
