Choose the correct order of bond angles for the following
Options:
A) x > z > y
B) x > y > z
C) z > y > x
D) y > x > z
Show Answer
Answer:
Correct Answer: B
Solution:
- Idea This problem includes conceptual mixing of bond angle in a molecule and the bent rule. To solve this issue -Draw the structure of the given compounds. -apply the bent rule and choose the correct answer. Bent rule According to bent rule, As the electronegativity of terminal atom increases, bond angle decrease. This is due to presence of more electron density towards electronegative atom. Bond angle $ \frac{1}{\text{Electronegativity of terminal atom}} $ Electronegativity of terminal atom increases. Bond angle decreases. TEST Edge Similar problems including bond angle, bond distance and reactivity of compound are also asked in JEE Main generally. So students are advised to study Bent’s rule, VSEPR theory and Drago rule also.
