The bond order of the N?0 bonds in \[NO_{3}^{-}\] ion is

A)  0.33                      

B)  1.00 

C)  1.33                                      

D)  1.50

Correct Answer: C

Solution :

                 The resonating structures of N03 ions are as                 Thus, N?0 bond order          \[=\frac{number\text{ }of\text{ }bonds\text{ }between\text{ }two\text{ }atoms}{total\text{ }number\text{ }of\text{ }resonating\text{ }structures}\]                 \[=\frac{4}{3}=1.33\]
