Match List-I with List-IIList-I (Compound) List-II (Shape) (A) \(BrF_5\) (I) bent (B) \([CrF_6]^{3–}\) (II) square pyramidal (C) \(O_3\) (III) trigonal bipyramidal (D) \(PCI_5\) (IV) octahedral
Choose the correct answer from the options given below :
| List-I (Compound) | List-II (Shape) |
|---|---|
| (A) \(BrF_5\) | (I) bent |
| (B) \([CrF_6]^{3–}\) | (II) square pyramidal |
| (C) \(O_3\) | (III) trigonal bipyramidal |
| (D) \(PCI_5\) | (IV) octahedral |
- (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
- (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
The Correct Option is C
Solution and Explanation
The correct matching is:
(A) \(BrF_5\) – square pyramidal
(B) \([CrF6]^{3–}\) – octahedral
(C) \(O_3\) - bent
(D) \(PCI_5\) – trigonal bipyramidal
So, the correct option is (C): (A)-(II), (B)-(IV), (C)-(I), (D)-(III).

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
