1 Chemical Bonding and Molecular Structure

In the formation of N₂⁺ from N₂, the electron is removed from

1) a p * orbital

2) a s * orbital

3) a p orbital

4) a s orbital

Option 1

Option 2

Option 3

Option 4 Solution:

SOLUTION

In the formation of N2+? from N2?, the electron is lost from a σ-orbital.

M.O configuration of N2? is:

σ1s²σ∗1s²,σ2s²σ∗2s²,π2py²?π2pz²,σ2p²

M.O configuration of N2+? is:
σ1s²σ∗1s²,σ2s²σ∗2s²,π2py²?,π2pz²?,σ2px^₁?

Hence, 2 electrons are removed from σ- orbital.
