MCQ
The molecule having the largest bond angle is
- ✓$H_2O$
- B$H_2S$
- C$H_2Se$
- D$H_2Te$
✓
Answer
Correct option: A.
$H_2O$
a
As the electronegativity of the central atom decreases, the repulsions between element-hydrogen bond pairs decreases and hence the angle decreases accordingly. Thus, $H _2 O$ has the largest bond angle $\left(104.5^{\circ}\right)$.
