The bond angle of H 2 Se is best described as
Options
- ABetween 109 o and 120 o
- BGreater than 120 o
- CLess than that in H 2 S but not less than 90 o
- DLess than 90 o
Correct answer
C. Less than that in H 2 S but not less than 90 o
Step-by-step solution
According to Drago's rule : ∠ HXH : H 2 O 1 0 4 o > H 2 S 9 2 o > H 2 Se 9 1 o > H 2 Te 8 9 · 5 o
