Toppr Admin · Accepted Answer

Be2 molecule has MO electronic configuration KK-x3C3-s-2-x3C3-x2217-2s-2-The bond order is 2-x2212-22-0-Zero bond order indicates that Be2 molecule does not exists-

Use molecular orbital theory to explain why $B e_{2}$ molecule does not exist.

$B e_{2}$ molecule has MO electronic configuration $K K (σ s)^{2} (σ^{*} 2 s)^{2}$ .

The bond order is $\frac{2 - 2}{2} = 0$ .

Zero bond order indicates that $B e_{2}$ molecule does not exists.
