Question

What is the formal charge of carbon in CO?|C≡O|​

Answer 1

Answer:

FC of C = -1

General Formulas and Concepts:

• Lewis Dot Structures
• Resonance Structures
• Formal Charge: FC = # of valence e⁻ - # of lone e⁻ - # of bonds

Explanation:

Step 1: Define

Carbon (C)

• 4 valence e⁻
• 2 lone e⁻
• 3 bonds

Oxygen (O)

• 6 valence e⁻
• 2 lone e⁻
• 3 bonds

Step 2: FC of C

1. Substitute:                    FC = 4e⁻ - 2e⁻ - 3
2. Subtract:                       FC = -1
