The correct order of ONO bond angle in the given species is
The correct order of ONO bond angle in the given species is
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
For , the central nitrogen atom is hybridized with no lone pairs, resulting in a linear geometry and a bond angle of .
For , the central nitrogen atom is hybridized with one unpaired electron. The repulsion from a single electron is less than that from a bond pair, so the bond angle opens up to be greater than (approximately ).
For , the central nitrogen atom is hybridized with no lone pairs, resulting in a trigonal planar geometry and a bond angle of exactly .
For , the central nitrogen atom is hybridized with one lone pair. The lone pair-bond pair repulsion is greater than bond pair-bond pair repulsion, compressing the bond angle to less than (approximately ).
Therefore, the correct order of O-N-O bond angles is .
