Question

Use Molecular Orbital theory to determine the bond order in each of species, [He₂j⁺ and [He₂]²⁺?

पर्याय

• 1, 2

• \[\ce{0, 1/2}\]

• \[\ce{1/2, 1}\]

• 0, 1

Answer 1

\[\ce{1/2, 1}\]

Explanation:

He₂⁺(3) : σ ls² σ *1s¹

Bond order = \[\ce{1/2 (N_b - N_a) = 1/2 (2 - 1) = 1/2}\]

He₂²⁺(2) : σ 1s² 

B.O.: = \[\ce{1/2 [2 - 0] = 1}\]
