Which of the following has maximum number of l.p. at central atom?
ClO3-
SF4
XeF4
I3-
From the structure of the given species, It can be clearly seen that \(I_3^{-}\) has the maximum number of lone pairs at central atom.
So, the correct answer is option (D): \(I_3^{-}\)

Match List-I with List-II: List-I
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
