NEET · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Which amongst the following is incorrect statement?
- A \(C _{2}\) molecule has four electrons in its two degenerate \(\pi\) molecular orbitals.
- B \(H _{2}^{+}\)ion has one electron.
- C \(O _{2}^{+}\)ion is diamagnetic.
- D The bond orders of \(O _{2}^{+}, O _{2}, O _{2}^{-}\)and \(O _{2}^{2-}\) are \(2.5, 2, 1.5\) and \(1,\) respectively.
Answer & Solution
Correct Answer
(C) \(O _{2}^{+}\)ion is diamagnetic.
Step-by-step Solution
Detailed explanation
\(O _{2}^{+}\)ion is having \(15\) electrons, so it contain one unpaired electron. Hence it is paramagnetic in nature.
