In the nitrate ion, \[NO_{3}^{-}\]

A)  one \[N-O\] bond is shorter than the other two equal bonds

B)  one \[N-O\] bond is longer than the other two equal bonds

C)  all the \[N-O\] bonds are equal in length

D) all the \[N-O\] bonds are unequal in length

E) None of the above

Correct Answer: C

Solution :

The resonating structure of nitrate ion \[(NO_{3}^{-})\]is As a result of resonance, the bond lengths of\[N-O\] bond in a molecule becomes equal.
