Q. What is the formal charge on carbon atom in the following two structure:

$0, - 2$

$0, 0$

$+ 2, - 2$

$+ 1, - 1$

Formal charge on $C$ atom = Valence electrons
-Lone pair of electrons $- \frac{1}{2} \times$ Bonding electrons
$= 4 - 0 - \frac{1}{2} \times 8 = 0$
Similarly, formal charge on $C$ atom $= 0$

Q. What is the formal charge on carbon atom in the following two structure:

0,−2

0,0

+2,−2

+1,−1

Formal charge on C atom = Valence electrons -Lone pair of electrons −21​× Bonding electrons =4−0−21​×8=0 Similarly, formal charge on C atom =0

$0, - 2$

$0, 0$

$+ 2, - 2$

$+ 1, - 1$

Formal charge on $C$ atom = Valence electrons
-Lone pair of electrons $- \frac{1}{2} \times$ Bonding electrons
$= 4 - 0 - \frac{1}{2} \times 8 = 0$
Similarly, formal charge on $C$ atom $= 0$
