આયનો/અણુઓને ધ્યાનમાં લો.
$O _{2}^{+}, O _{2}, O _{2}^{-}, O _{2}^{2-}$
ચઢતા બંધક્રમાંકનો સાચો વિકલ્પ શોધો.
A
$O _{2}^{2-}< O _{2}^{-}< O _{2}< O _{2}^{+}$
B
$O _{2}^{-}< O _{2}^{2-}< O _{2}< O _{2}^{+}$
C
$O _{2}^{-}< O _{2}^{2-}< O _{2}^{+}< O _{2}$
D
$O _{2}^{-}< O _{2}^{+}< O _{2}^{2-}< O _{2}$
(JEE MAIN-2022)
Solution
| ion/molecule | Number of $e^{-}$ BMO | Number of $e^{-}$ in ABMO | Bond order |
| $O _{2}{ }^{+}$ | $10$ | $5$ | $2.5$ |
| $O _{2}{ }$ | $10$ | $6$ | $2$ |
| $O _{2}{ }^{-}$ | $10$ | $7$ | $1.5$ |
| $O _{2}{ }^{-2}$ | $10$ | $8$ | $1$ |
Bond order $O _{2}{ }^{2-}< O _{2}{ }^{-}< O _{2}< O _{2}{ }^{+}$
