# Problem: Draw a Lewis structure and add formal charges to each resonance form of HCNO.

###### FREE Expert Solution
• N : prefers a complete octet, more likely to have a +1 formal charge (more stable)
• O : prefers a complete octet, more likely to have a -1 formal charge (more stable)
• C : prefers a complete octet, more likely to have a 0 formal charge (more stable)

a) Formal charge of N

F.C. of N = 5 – (4 + 0) = +1

Formal charge of O

F.C. of O = 6 – (3 + 2) = +1

Formal charge of C

F.C. of C = 4 – (2 + 4) = -2

Overall charge

Overall = 1+1-2 = 0
