Question

What is the formal charge on carbon atom in the following two structures:

$: \ddot { \mathrm { s } } = \mathrm { C } = \ddot { \mathrm { s } }$

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

Answer 1

Answer: (B)

0, 0

Answer 2

: $:\ddot{S} = C = \ddot{S}:$

Formal charge on C atom = Valence electrons

- Lone pair of electrons $- \frac{1}{2}$× Bonding electrons

$= 4 - 0 - \frac{1}{2} \times 8 = 0$

Formal charge on C atom = 0
