N 2 and O 2 are converted to mono cations N 2 + and O 2 + respectively. The wrong statement with respect to given changes in the following is
Options
- Athe N – N bond weakens
- Bthe O – O bond order increases
- Cthe O - O bond length decreases
- DN 2 + becomes diamagnetic
Correct answer
D. N 2 + becomes diamagnetic
Step-by-step solution
B.O or N 2 = 3 and N 2 + = 2.5 As here bond order decreases so N - N bond get weak N 2 + becomes paramagnetic In case of O 2 and O 2 + B.O or O 2 = 2 and O 2 + = 2.5 as bond order increases so O - O bond length decreases.
