1. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
2. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
3. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
4. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)

Correct answer: (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Solution

BrF5 has a square pyramidal shape due to its five bonding pairs and one lone pair, while [CrF6]3− adopts an octahedral geometry with six bonding pairs. O3 is bent because of its two bonding pairs and one lone pair, and PCl5 has a trigonal bipyramidal shape with five bonding pairs.
