Unshared, or lone, electron pairs play an important role in determining the chermical 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
HyC
CH
The number of unshared pairs at atom e is
The number of unshared pairs at atom a is
The number of unshared pairs at atom b is
HC
CH
The number of unshared pairs at atom e is
Determine the number of lone pairs (if any) on each oxygen, nitrogen and charged carbon atoms in the following structures.
Following the rule that each atom of carbon, oxygen, and nitrogen reacts to achieve a complete outer shell of eight valence electrons, add unshared pairs of electrons as necessary to complete the valence shell of each atom in these ions. Then assign formal charges as appropriate.
