Detailed Solution

Concept- We must first anticipate the structure of the molecule in order to calculate the bond angle of the molecule. The number of valence electrons in the molecule must first be determined. Iodine and fluorine are the two atoms in

, and as both of them are group 17 elements, they both have seven electrons in their valence shells. Additionally, there is one negative charge, meaning that the total number of valence electrons in the molecule has increased by one. Thus, there are 7+7+7+7+7+1=36 valence electrons in total.
As a result, of the four covalent connections created by the four fluorine atoms bonded to the iodine, each fluorine atom will have three lone pairs. This totals 28 electrons, while the remaining 4 electrons make up the two lone pairs that surround the atom of iodine. Iodine will therefore have a coordination number of 6, of which 2 lone pairs and 4 covalent bonds are present. It will have a square planar shape with fluorine atoms occupying all four corners, one lone pair above the plane, and one lone pair below the plane. The framework is provided below:
