What is the number of electrons present in antibonding orbitals of \(\mathrm{N}_2\) molecule according to molecular orbital theory?
  1. 14
  2. 04
  3. 10
  4. 06

Solution

The electronic configuration of \(\mathrm{N}_2\) molecule is \((\sigma 1 \mathrm{~s})^2\left(\sigma^* 1 \mathrm{~s}\right)^2(\sigma 2 \mathrm{~s})^2\left(\sigma^* 2 \mathrm{~s}\right)^2\left(\pi 2 \mathrm{p}_{\mathrm{x}}\right)^2\left(\pi 2 \mathrm{p}_{\mathrm{y}}\right)^2\left(\sigma 2 \mathrm{p}_{\mathrm{z}}\right)^2\) \(\therefore \quad\) No. of electrons in antibonding orbitals \(=4\)
