Question

STABILITY of the species Li2 , Li2- and Li2+ increases in what order?​

Answer 1

Li2+ is more stable than Li2− because Li2− has more numbers of antibonding electrons. Li2+ is more stable than Li2− because Li2− has more numbers of antibonding electrons. The species in which the N atom is in a state of sp hybridization is: NO.

Answer 2

Answer:

The stability order is Li₂>Li₂⁺>Li₂⁻.

Explanation:

The bond order of a molecule is directly proportional to its stability.

Case A: Li₂

The total number of electrons in the molecular orbitals of Li₂=6

The bond order of Li₂=1

Case B: Li₂⁻

The total number of electrons in the molecular orbitals of Li₂⁻=7

The bond order of  Li₂⁻=0.5

Case C: Li₂⁺

The total number of electrons in the molecular orbitals of Li₂⁺=5

The bond order of  Li₂⁺=0.5

The stability of is Li₂⁻ less than Li₂⁺ because higher interelectronic repulsion is present in Li₂⁻.

So, the stability order is,

Li₂>Li₂⁺>Li₂⁻.
