(a)
Interpretation:
The formal charges of element A if it was in (a) Group 7A, (b) Group 5A, (c) Group 3A should be drawn.
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.
- Formal charge of an atom can be determined by the given formula.
To determine: Formal charge of the given species
(a)
Answer to Problem 5PPC
Explanation of Solution
Given Lewis structure
A formal charge (FC) is the charge assigned to an atom in a molecule, irrespective of relative electronegativity.
The formal charge of the given species is calculated,
- If A is group 7A, then number of valence electrons is 7
Substituting these values to the equation,
- If A is group 5A, then number of valence electrons is 5
Substituting these values to the equation,
- If A is group 3A, then number of valence electrons is 3
Substituting these values to the equation,
Therefore,
The formal charges are,
