Question

The isostructural species among the following are:

• A. $S{O}_4^{2-}$ and $B{F}_4^{-}$
• B. $N{H}_3$ and $N{H}_4^{+}$
• C. $C{O}_3^{2-}$ and $C{O}_2$
• D. $C{H}_4$ and $B{F}_3$

Answer 1

Answer: (A)

$S{O}_4^{2-}$ and $B{F}_4^{-}$ have $s{p}^3$ hybridisation and are tetrahedral in shape.
