Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organiccompounds. 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.H₂CH₂b HcNCH2The number of unshared pairs at atom a isThe number of unshared pairs at atom b isThe number of unshared pairs at atom c isThe number of unshared pairs at atom a is 1 vThe number of unshared pairs at atom b is OvThe number of unshared pairs at atom c is 1.
