Step 1: Before diving into the molecular geometries of the given compounds, let's review the basic concepts:. Step 2: . Central atom: The atom in the molecule connected to all the other atoms is called the central atom. Step 3: . Electron pairs: The central atom is surrounded by electron pairs, which could be bonding pairs (forming covalent bonds) or lone pairs (not forming bonds). Step 4: . Steric number: The total number of electron pairs around the central atom is called the steric number. Step 5: . Molecular geometry: The arrangement of atoms in a molecule is called the molecular geometry, which is determined by the steric number and the distribution of bonding and lone pairs. Now, let's determine the molecular geometries of the given compounds: Step 6: . ClF4+: The central atom Cl has 4 electron pairs, with 3 bonding pairs and 1 lone pair. The molecular geometry is seesaw (AX₄E). Step 7: . COCl2: The central atom C has 3 electron pairs, with 2 bonding pairs and 1 lone pair. The molecular geometry is trigonal planar (AX₂E). Step 8: . XeF4: The central atom Xe has 4 electron pairs, with 4 bonding pairs and no lone pairs. The molecular geometry is square planar (AX₄). Step 9: . IF3: The central atom I has 3 electron pairs, with 3 bonding pairs and no lone pairs. The molecular geometry is trigonal bipyramidal with a seesaw shape (AX₃). Step 10: . IO2F2-: The central atom I has 4 electron pairs, with 2 bonding pairs and 2 lone pairs. The molecular geometry is tetrahedral with a seesaw shape (AX₂E₂). Final Answer: The molecular geometries are (1) seesaw, (2) trigonal planar, (3) square planar, (4) T-shaped, and (5) seesaw, respectively.
