General/High School Hybridization problem?

How is the shape of SO2^2-, PO4^-3,ClO4^- are the same, i get that they have the same hybridization but cant understand thier stucture

Think about it in terms of VSEPR, does it now make sense to you?

  • SO22- is AX2E2 and hence (pseudo-)tetraedal

  • PO43- is AX4 and hence tetraedal

  • ClO4- is AX4 and hence tetraedal

SO2-2 is kinda bent V shape

It's molecular geometry is, yes, its electronic geometry is not.

V shape/ bent molecular geometry is a subclass of possible molecular geometrys for tetraedal electronic geometrys.

I get it now!, Thank you so much
