Question

write in any formal charges not equal to zero. if there are none, please check the box below. there are no missing formal charges.

Explanation:

Step1: Recall formal - charge formula

Formal charge ($FC$) = Valence electrons - Non - bonding electrons - $\frac{1}{2}$ Bonding electrons.

Step2: Calculate formal charge of N

N has 5 valence electrons. In the structure, it has 2 non - bonding electrons and 6 bonding electrons. $FC_N=5 - 2-\frac{6}{2}=5 - 2 - 3=0$.

Step3: Calculate formal charge of C

C has 4 valence electrons. It has 0 non - bonding electrons and 8 bonding electrons. $FC_C=4 - 0-\frac{8}{2}=4 - 4 = 0$.

Step4: Calculate formal charge of O

O has 6 valence electrons. It has 2 non - bonding electrons and 6 bonding electrons. $FC_O=6 - 2-\frac{6}{2}=6 - 2 - 3=1$.

Answer:

The formal charge on O is + 1.
