Question

The formal charges of atoms (1), (2) and (3) in the ion $\left[ \mathrm{O} = \mathrm{N} = \mathrm{O} \right]^+$ are

• A. $0, +2, -1$
• B. $0, +1, 0$
• C. $+2, 0, -1$
• D. $+1, 0, 0$

Hint:

Formal charges help determine the most stable Lewis structure by minimizing charge separation.

Answer 1

The Correct Option is B

Formal charge formula: $FC = V - (L + \frac{B}{2})$, where $V$ is valence electrons, $L$ lone pairs, $B$ bonding electrons. Calculate for each atom accordingly.
