(a)
Interpretation:
The group of element A if its formal charge is zero should be identified.
Concept Introduction:
- A formal charge (FC) is the charge assigned to an atom in a molecule, irrespective of relative electronegativity by thinking that electrons in all
chemical bonds are shared equally among atoms. - This method is used to identify the most probable Lewis structures if more than one possibility exists for a compound.
- The Lewis structure with formal charge on each of the atoms close to zero is taken as the most plausible structure.
- Formal charge of an atom can be determined by the given formula.
To find: The group of element A it its formal charge is zero.
(b)
Interpretation:
The group of element A if its formal charge is zero should be identified.

- The Lewis structure of acetone is Circling the carbonyl carbon, i.e., the carbon atom attached to oxygen, and its octet gives Circling the oxygen atom and its octet gives Thus, atoms share electrons in making bonds, and a pair of electrons may be included in the octet of two different atoms. When computing the formal charge on an atom, the number of electrons that belong to that atom is compared with the number of electrons the atom would have in the unbonded and neutral state. If the two numbers are the same, the formal charge on the atom is zero. In a Lewis structure both electrons in an unshared pair belong to the atom, and one of every pair of shared (bonding) electrons belongs to the atom.arrow_forwardWhich of the ions gives a formal charge that is an accurate picture of where the charge really is?arrow_forwardDetermine the formal charge on each atom in the structure.arrow_forward

Three bonding structures are possible, depending on which is the central atom: NSF, SNF, and SFN. (a) Write a Lewis diagram for each of these molecules, indicating the formal charge on each atom. (b) Often, the structure with the least separation of formal charge is the most stable.
