What is the molecular geometry shape and hybridization central atom for PF5, ClF3, CO2-3, SF-5, I-3?

Question

How to find the molecular geometry shape and what are they to see if I got it correct as well as the hybridization of the central atom. Clear answer to all of them and what are the answers. I need clarification that I have solved them correctly.

Answer 1

1st you need draw Lewis Dot structures for each compound or ion, then you need to check the central atom that has how many bonding pairs and lone pairs to predict the molecular shapes. Remember that s sublevel has one orbital, p has 3 orbitals and d has 5 orbitals. For each of the compound and ion, the answers are following: (a couple of ions, some typos that might cause some confusion)

PF₅ the central atom P has 5 bond pairs, the shape is trigonal bipyramidal and habridization is sp³d

ClF₃ the central atom Cl has 3 bond pairs and 2 lone pairs, the shape is T-shape and habridization is sp³d

CO₃^2- the central atom C has 3 bond pairs (2 sigle bonds and 1 double bond. π bond does not count in molecular shape), the shape is trigonal planar and habridization is sp²

SF₅^-1 the central atom S has 4 bond pairs and one lone pair, the shape is square pyramidal and habridization is sp³d²

I^3- the central atom I has 2 bond pairs and 3 lone pairs, the shape is linear and habridization is sp³d
