Vedclass · Answer

(D) To be isostructural,planar,and non-polar,the species must have the same hybridization and geometry.$1$. $I_3^-$: Central atom $I$ has $7$ valence electrons + $1$ (negative charge) + $2$ (from $2$ $I$ atoms) = $10$ electrons,divided by $2$ gives $5$ electron pairs ($sp^3d$ hybridization). It has $3$ lone pairs in the equatorial position,resulting in a linear geometry $(180^{\circ})$,which is planar and non-polar.$2$. $HgCl_2$: $Hg$ has $2$ valence electrons,forming $2$ bonds with $Cl$. It has $sp$ hybridization,resulting in a linear geometry $(180^{\circ})$,which is planar and non-polar.$3$. $XeF_2$: Central atom $Xe$ has $8$ valence electrons + $2$ (from $2$ $F$ atoms) = $10$ electrons,divided by $2$ gives $5$ electron pairs ($sp^3d$ hybridization). It has $3$ lone pairs in the equatorial position,resulting in a linear geometry $(180^{\circ})$,which is planar and non-polar.All three species are linear,planar,and non-polar.

Which of the following species are isostructural,planar,and non-polar?
