Question

The bond angle $H-O-H$ in ice is closest to:

• A. ${120}^o{28}^{\prime }$
• B. ${60}^o$
• C. ${90}^o$
• D. ${109}^o$

Answer 1

The correct option is D ${109}^o$

Image 2- In Ice

In ice the molecules live up to form a network & every lone pair has a hydrogen from neighboring molecule very close to it and attracts the lone pair from the oxygen atom & increases the bond angle.
