Question

According to $M.O.T.$ electronic configuration of $\mathrm{C}_{2}$ molecule is

$\sigma 1 \mathrm{s}^{2}<\sigma^{*} 1 \mathrm{s}^{2}<\sigma 2

Vedclass · Accepted Answer

$C_2$

Vedclass · Answer

According to $M.O.T.$ electronic configuration of $\mathrm{C}_{2}$ molecule is

$\sigma 1 \mathrm{s}^{2}<\sigma^{*} 1 \mathrm{s}^{2}<\sigma 2 \mathrm{s}^{2}<\sigma^{*} 2 \mathrm{s}^{2}<\pi_{2} \mathrm{p}_{\mathrm{x}}^{2}=\pi_{2} \mathrm{p}_{\mathrm{y}}^{2}$

so, $\mathrm{C}_{2}$ molecule contain only $\pi$ bond
