a) \(\textrm{formal charge} = \# e^{-} \textrm{ in periodic table} - \# e^{-} \textrm{nonbonding} - \frac{\# e^{-} \textrm{in bonds}}{2}\)
\[\textrm{formal charge} = 4-1- \frac{6}{2} =0 \nonumber\]
b) \(\textrm{formal charge} = \# e^{-} \textrm{ in periodic table} - \# e^{-} \textrm{nonbonding} - \frac{\# e^{-} \textrm{in bonds}}{2}\)
\[\textrm{formal charge} = 5-3- \frac{4}{2} =0 \nonumber\]
c) \(\textrm{formal charge} = \# e^{-} \textrm{ in periodic table} - \# e^{-} \textrm{nonbonding} - \frac{\# e^{-} \textrm{in bonds}}{2}\)
\[\textrm{formal charge} = 6-5- \frac{2}{2} =0 \nonumber\]
