(b) : $\mathrm{NF}_{3}$ (pyramidal) and $\mathrm{BF}_{3}$ (trigonal planar)\ $\mathrm{BF}_{4}^{-}$(tetrahedral) and $\mathrm{NH}_{4}^{+}$(tetrahedral)\ $\mathrm{BCl}_{3}$ (trigonal planar) and $\mathrm{BrCl}_{3}$ (trigonal bipyramidal)\ $\mathrm{NH}_{3}$ (pyramidal) and $\mathrm{NO}_{3}^{-}$(trigonal planar)\ Thus, $\mathrm{BF}_{4}^{-}$and $\mathrm{NH}_{4}^{+}$are isostructural species.
