Question

The geometrical arrangement and shape of I3- are respectively (A) trigonal bipyramidal geometry, linear shape (B) hexagonal geometry, T-shape (C) triangular planar geometry, triangular shape (D) tetrahedral geometry, pyramidal shape

I3-⇒ 2 2 bond pairs + 3 lone pairs =5 hybrid orbitals. Thus, hybridisation is sp3d and geometrical arrangement is trigonal bipyramidal. However, its shape is linear because of the presence of three lone pairs of electrons.

Q. The geometrical arrangement and shape of $I_{3}^{-}$ are respectively

trigonal bipyramidal geometry, linear shape

hexagonal geometry, T-shape

triangular planar geometry, triangular shape

tetrahedral geometry, pyramidal shape

$I_{3}^{-} \Rightarrow 2$
2 bond pairs + 3 lone pairs =5 hybrid orbitals. Thus, hybridisation is
$s p^{3} d$ and geometrical arrangement is trigonal bipyramidal. However, its shape is linear because of the presence of three lone pairs of electrons.
