What is the number of electrons in bonding molecular orbitals and antibonding molecular orbitals respectively in \(\mathrm{F}_2\) molecule.
- A 12 and 6
- B 10 and 8
- C 8 and 10
- D 6 and 12
Answer & Solution
Correct Answer
(B) 10 and 8
Step-by-step Solution
Detailed explanation
\( \text{Total electrons in F}_2 = 2 \times 9 = 18 \). \( \text{MO configuration: } \sigma_{1s}^2 \sigma_{1s}^{*2} \sigma_{2s}^2 \sigma_{2s}^{*2} \sigma_{2p_z}^2 \pi_{2p_x}^2 \pi_{2p_y}^2 \pi_{2p_x}^{*2} \pi_{2p_y}^{*2} \).
