Question

Stability of the species Li₂, $Li_2^-$ and $Li_2^+$ increases in the order of :
(a) Li₂ < $Li_2^+$ < $Li_2^-$
(b) $Li_2^-$ < $Li_2^+$ < Li₂
(c) Li₂ < $Li_2^-$ < $Li_2^+$
(d) $Li_2^-$ < Li₂ < $Li_2^+$

Answer 1

Answer:

Explanation:bond order increases stability increase. Here bond order or Li2 is 1 Li2+ is 0.5 and Li2- is 0.5. So Li2 is having high bond order among these ions. So correct order is b
