Question

The electronic configuration of carbon is 1s2 2s2 2p2. There are 12 electrons in C2. The correct electronic configuration of C2 molecule is (A) (σ 1s2)(σ* 1s2)(σ 2s2)(σ* 2s2)(σ 2pz2)(π 2px2) (B) (σ 1s2)(σ* 1s2)(σ 2s2)(σ* 2s2)(π 2px2 = π2py2) (C) (σ 1s2)(σ* 1s2)(σ 2s2)(σ* 2s2)(σ 2pz2) (π 2px1 = π2py1) (D) (σ 1s2)(σ* 1s2)(σ 2s2)(σ* 2s2) (π 2px2 = π2py1)

For atoms like nitrogen and below N in atomic number have higher energy for pz -orbital, hence the configuration for C2 molecule is (σ 1s2)(σ* 1s2)(σ 2s2)(σ* 2s2) (π 2px2 = π2py2).

Q. The electronic configuration of carbon is $1 s^{2} 2 s^{2} 2 p^{2}$ . There are $12$ electrons in $C_{2}$ . The correct electronic configuration of $C_{2}$ molecule is

$(σ 1 s^{2}) (σ^{} 1 s^{2}) (σ 2 s^{2}) (σ^{} 2 s^{2}) (σ 2 p_{z}^{2}) (π 2 p_{x}^{2})$

$(σ 1 s^{2}) (σ^{} 1 s^{2}) (σ 2 s^{2}) (σ^{} 2 s^{2}) (π 2 p_{x}^{2} = π 2 p_{y}^{2})$

$(σ 1 s^{2}) (σ^{} 1 s^{2}) (σ 2 s^{2}) (σ^{} 2 s^{2}) (σ 2 p_{z}^{2}) (π 2 p_{x}^{1} = π 2 p_{y}^{1})$

$(σ 1 s^{2}) (σ^{} 1 s^{2}) (σ 2 s^{2}) (σ^{} 2 s^{2}) (π 2 p_{x}^{2} = π 2 p_{y}^{1})$

For atoms like nitrogen and below $N$ in atomic number have higher energy for $p_{z}$ -orbital, hence the configuration for $C_{2}$ molecule is
$(σ 1 s^{2}) (σ^{} 1 s^{2}) (σ 2 s^{2}) (σ^{} 2 s^{2}) (π 2 p_{x}^{2} = π 2 p_{y}^{2})$ .
