Question

Among the following species identify the isostructural pairs :

$N{H}_3,N{O}_3^{-},B{F}_3,H_3{O}^{+},H{N}_3$

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

Answer 1

The correct option is C

$[N{F}_3,H_3{O}^{+}]and[N{O}_3^{-},B{F}_3]$

$N{F}_3$ and $H_3{O}^{+}$ have $s{p}^3$ hybridization so they are pyramidal in shape.

$N{O}_3^{-}$ and $B{F}_3$ have $s{p}^2$ hybridization so they are trigonal planar in shape.
