Question
Chapter 1, Problem 1.51P
Interpretation Introduction
Interpretation:
The formal charge on each atom in the given species is to be determined.
Concept introduction:
The formal charge on an atom in a molecule or a polyatomic ion is determined from the group number of the atom and its actual valence electrons. The valence electrons are assigned on the basis of electrons shared in a covalent bond and lone pairs. If an atom bears one or more lone pairs, both the electrons in each lone pair are assigned to the atom which bears them. Each atom in a covalent bond is assigned with half of the shared electrons.

(References
Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic
compounds. Thus, it is important to know which atoms carry unshared pairs.
Use the structural formulas below to determine the number of unshared pairs at each designated atom.
Be sure your answers are consistent with the formal charges on the formulas.
The number of unshared pairs at atom a is
The number of unshared pairs at atom b is
The number of unshared pairs at atom c is
The number of unshared pairs at atom a is
The number of unshared pairs at atom b is
The number of unshared pairs at atom e is
