MCQ
The bond angle between ${H - O -H}$ in ice is closest to
- A${120^o}28'$
- B${60^o}$
- C${90^o}$
- ✓${105^o}$
✓
Answer
Correct option: D.
${105^o}$
d
In ice the molecules live up to form a network and every lone pair has a hydrogen from neighboring molecule very close to it and attracts the lone pair from the oxygen atom and increases the bond angle.
