Of the species,

Question:

Of the species, $\mathrm{NO}, \mathrm{NO}^{+}, \mathrm{NO}^{2+}, \mathrm{NO}^{-}$, the one with minimum bond strength is :

 

  1. $\mathrm{NO}^{2+}$

  2. $\mathrm{NO}^{+}$

  3. $\mathrm{NO}$

  4. $\mathrm{NO}^{-}$


Correct Option: , 4

Solution:

Bond order of $\mathrm{NO}^{2+}=2.5$

Bond order of $\mathrm{NO}^{+}=3$

Bond order of $\mathrm{NO}=2.5$

Bond order of $\mathrm{NO}^{-}=2$

Bond order $\alpha$ bond strength.
