MCQ
Which of the following statements is correct?
  • ✓
    In the formation of dioxygen from oxygen atoms $10$ molecular orbitals will be formed.
  • B
     All the molecular orbitals in the dioxygen will be completely filled.
  • C
     Total number of bonding molecular orbitals will not be same as total number of anti bonding orbitals in dioxygen.
  • D
    Number of filled bonding orbitals will be same as number of filled anti bonding orbitals.
✓

Answer

Correct option: A.
In the formation of dioxygen from oxygen atoms $10$ molecular orbitals will be formed.
$\ce{O_2 = (8 + 8) = 16.}$
$\sigma1\text{s}^{2} < \sigma^{*}1\text{s}^{2} < \sigma2\text{s}^{2} < \sigma\text{s}^{2} < \sigma2\text{s}$
