4.Chemical Bonding and Molecular Structure
hard
Which of the following order of bond strength is correct ?
A
$O_2^ - > {O_2} > O_2^ + $
B
$O_2^ - < {O_2} < O_2^ + $
C
$O_2^ - > {O_2} < O_2^ + $
D
$O_2^ - < {O_2} > O_2^ + $
Solution
The bond order for $O _2^{-}, O _2, O _2^{+}$are $1.5, 2.0, 2.5,$ respectively. The higher is bond order, the more is bond energy
Hence, the bond strength in $O _2^{+}, O _2, O _2^{-}$ follows the order $O _2^{+}> O _2>$ $O _2^{-}$
So, the correct option is $B.$
