Which of the following has the minimum bond length?
A.
$$O_2^ - $$
B.
$$O_2^{2 - }$$
C.
$${O_2}$$
D.
$$O_2^ + $$
Answer :
$$O_2^ + $$
Solution :
Bond order of $$O_2^ + = \frac{{10 - 5}}{2} = 2.5$$
Bond order of $$O_2^ - = \frac{{10 - 7}}{2} = 1.5$$
Bond order of $$O_2^{2 - } = \frac{{10 - 8}}{2} = 1$$
Bond order of $${O_2} = \frac{{10 - 6}}{2} = 2$$
$$\because $$ Maximum bond order = minimum bond length.
∴ Bond length is minimum for $$O_2^ + $$
