Question

What is the approximate h−o⋅⋅⋅⋅h bond angle in ice, where h−o is the covalent bond and o⋅⋅⋅⋅h is the hydrogen bond?

Answer 1

Hello there.

What is the approximate h−o

109.47°

Answer 2

The H-O bond angle for ice is 109.47° and for liquid water, the bond angle of H-O is 105°. The bond angle for ice is wider than for liquid water because the structure of ice is stable when the bond angle between H and O is wider. This is the reason why liquid water expands when it turns to ice.
