Expert Answer:
In formal charge (FC) is the charge assigned to an atom in a molecule and we assumed that electrons in a chemical bond are shared equally between atoms, regardless of relative electronegativity and the counting of electrons is based on the assumption that the atom in the molecule owns 1 electron of each shared pair and both the electrons of the lone pair.
The formal charge of any atom in a molecule can be calculated by the following equation:
- FC = V - L- B/2
- where as,
- FC=formal charge
- V=Valence electron
- L=Lone Pair of electrons
- B=Bond pair electrons
The formal charge of any atom in a molecule can be calculated by the following equation:
