Question
Stability of the species Li2, Li2- and Li2+increases in the order of :-
Options
A.Li2 < Li2+ < Li2-
B.Li2- < Li2+ < Li2
C.Li2 < Li2- < Li2+
D.Li2- < Li2 < Li2+
Solution
Stability depends upon bond order
B.O. of Li2, Li2+ and Li2- are 1, 0.5 and 0.5 respectively.
Hence Li2 > Li2+
Li2 > Li2-
while Li2+ > Li2- due to higher inter electronic repulsion in Li2- which makes it least stable. Hence the order is Li2 > Li2+ > Li2-
