Vedclass · Answer

(A) When $KI$ and $I_2$ react,they form $KI_3$ as follows:$KI + I_2 \rightarrow KI_3$The species $KI_3$ dissociates into $K^+$ and $I_3^-$ ions.The central iodine atom in the $I_3^-$ ion has $3$ lone pairs and $2$ bond pairs.According to $VSEPR$ theory,the hybridization is $sp^3d$,which corresponds to a trigonal bipyramidal electron geometry.Since there are $3$ lone pairs occupying the equatorial positions,the remaining $2$ bond pairs are at the axial positions,resulting in a linear shape.Therefore,the shape of the $I_3^-$ ion is linear.
