What is the formal charge on carbon atom...

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

A

`0, -2`

B

`0,0`

C

`+2,-2`

D

`+1,-1`

Text Solution

Verified by Experts

The correct Answer is:
B

`:overset(..)(S) =C = overset(..)(S) :`
Formal charge on C atom = Valence electrons
- Lone pair of electrons ` - 1/2 xx` Bonding electons ` = 4 - 0 - 1/2 xx 8 = 0`
Similarly formal charge on C atom = 0
