Classify the following species as electrophiles (E) and nucleophiles (N) in routine organic synthesis
\[ \begin{array}{llllll} \mathrm{SO}_{3} & \mathrm{Cl}^{+} & \mathrm{CH}_{3} \mathrm{NH}_{2} & \mathrm{H}_{3} \mathrm{O}^{+} & \mathrm{BH}_{3} & \mathrm{CN}^{-} \end{array} \]
(a)$\mathrm{E}=\mathrm{SO}_{3}, \mathrm{Cl}^{+}, \mathrm{BH}_{3} ; \mathrm{N}=\mathrm{CH}_{3} \mathrm{NH}_{2}, \mathrm{H}_{3} \mathrm{O}^{+}, \mathrm{CN}^{-}$
(b)$\mathrm{E}=\mathrm{Cl}^{+}, \mathrm{H}_{3} \mathrm{O}^{+} ; \mathrm{N}=\mathrm{SO}_{3}, \mathrm{CH}_{3} \mathrm{NH}_{2}, \mathrm{BH}_{3}, \mathrm{CN}^{-}$
(c)$\mathrm{E}=\mathrm{Cl}^{+}, \mathrm{H}_{3} \mathrm{O}^{+}, \mathrm{BH}_{3} ; \mathrm{N}=\mathrm{SO}_{3}, \mathrm{CH}_{3} \mathrm{NH}_{2}, \mathrm{H}_{3} \mathrm{O}^{+}, \mathrm{CN}^{-}$
(d)$\mathrm{E}=\mathrm{SO}_{3}, \mathrm{Cl}^{+}, \mathrm{H}_{3} \mathrm{O}^{+}, \mathrm{BH}_{3} ; \mathrm{N}=\mathrm{CH}_{3} \mathrm{NH}_{2}, \mathrm{CN}^{-}$
