Question

Which of the following is not isostructural with $SiC{l}_4$ ?

• A. $P{O}_4^{3-}$
• B. $N{H}_4^{+}$
• C. $SC{l}_4$
• D. $S{O}_4^{2-}$

Answer 1

Answer: (C)

$SC{l}_4$ is not isostructural with $SiC{l}_4$ because shows square planar structure due to involvement of repulsion between lone pair and bond pair of electrons.
$S{O}_4^{2-}$ shows tetrahedral structure due to $s{p}^3$ hybridisation.
$P{O}_4^{3-}$ shows tetrahedral structure due to $s{p}^3$ hybridisation.
$N{H}_4^{+}$ shows tetrahedral structure due to $s{p}^3$ hybridisation.
