Question

The bond length of the species O₂ , O₂⁺ , O₂⁻ are in the order of *​

Answer 1

The bond length of the species O₂ , O₂⁺ , O₂⁻ are in the order of *​

Explanation:

• We know that, Bond order and Bond length are inversely proportional to each other:  " As bond order increases,  bond length decreases ".

• The bond order of species are:

Bond order= (Number of bonding electron − Number of a.b. electron)/2.

For $O_2=\frac{10-6}{2} =2$

For$O^+_2=\frac{10-5}{2} =2.5$

For$O^-_2=\frac{10-7}{2} =1.5$

So, the bond order of the species is-

$O^+_2>O_2>O^-_2$

And the order of the bond length of the species is the inverse of the order of the bond order.

$O^+_2<O_2<O^-_2$.
