The basic geometry and shape of `I _(3) ^(-)` are respectively:

Options

A. Trigonal bipyramidal geometry, line shape
B. Hexagonal geometry, T-shape
C. Triangular planar geometry, triangular shape
D. Tetrahedral geometry, pyramidal shape

Answer

A

Explanation

X for `l_(3) ^(-) = (1)/(2) [ 7 2 -0 +1]= 5`
Hybridization of l in `l _(3) ^(-) is sp ^(3) d.`
Thus `l _(3) ^(-)` has trignal bipyramidal geometry with linear shape.
