Vedclass · Answer

(B) Isostructural species are those that have the same hybridization and the same geometry.$1$. $[NF_3]$ is pyramidal ($sp^3$ hybridization with one lone pair) and $[BF_3]$ is trigonal planar ($sp^2$ hybridization).$2$. $[BF_4^-]$ has $sp^3$ hybridization and tetrahedral geometry. $[NH_4^+]$ also has $sp^3$ hybridization and tetrahedral geometry. Thus,they are isostructural.$3$. $[BCl_3]$ is trigonal planar $(sp^2)$,while $[BrCl_3]$ is $T$-shaped ($sp^3d$ with two lone pairs).$4$. $[NH_3]$ is pyramidal $(sp^3)$,while $[NO_3^-]$ is trigonal planar $(sp^2)$.Therefore,the correct pair is $[BF_4^- 	ext{ and } NH_4^+]$.

Among the given species,identify the isostructural pairs.
