plz explain and describe the structure of the common form of ice.

Hi Nitisha,

 

In ice, each water molecule is tetrahedrally surrounded by four neighbouring H₂O molecules. In this geometry, oxygen atoms occupy the corners of a tetrahedron.

In ice, there are four hydrogen atoms around each oxygen atom. Two hydrogen atoms are bonded by covalent bonds, whereas the other two hydrogen atoms are linked by hydrogen bonds. This gives a three-dimensional structure with a number of vacant spaces. Owing to this open cage-like structure, ice has large volume. Consequently, its density is less than that of water and it floats on water.

 

@Sweta, Correct answer.

Thumbs up!

 

Cheers!!
