Question

Among the following species, identify the isostructural pairs. $N{F}_3$, $N{O}_3^{-}$, $B{F}_3$, $H_3{O}^{+}$, $N_{3}H$

• A. $[N{F}_3,N{O}_3^{-}]$ and $[B{F}_3,H_3{O}^{+}]$
• B. $[N{F}_3,N_{3}H]$ and $[N{O}_3^{-},B{F}_3]$
• C. $[N{F}_3,H_3{O}^{+}]$ and $[N{O}_3^{-},B{F}_3]$
• D. $[N{F}_3,H_3{O}^{+}]$ and $[N_{3}H,B{F}_3]$

Answer 1

Answer: (C)

Therefore, $N{F}_3$, $H_3{O}^{+}$ and $B{F}_3$, $N{O}_3^{-}$ pairs have same shape.
