If `I_2` is dissolved in aqueous KI, the intense yellow species `I_3^` is formed. The structure of `I_3^-` ion is

A

Square pyramidal

B

Trigonal bipyramidal

C

Octahedral

D

Pentogonal bipyramidal

Text Solution

Verified by Experts

The correct Answer is:
B
Total no. of valence electron in `I_(3)^(-) =7xx3+1=22`.
In triiodide ion, the central iodine atom is `sp^(3)d` hybridised in which the equatorial positions are occupied by lone pair and the axial positions by iodine. Hence the structure is linear.
