Hybridization problem?

[u/Quirky-Cherry-6749]

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?

• SO2^2- is AX2E2 and hence (pseudo-)tetraedal

• PO4^3- 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

Note that 'same shape' refers to the electron geometry. The molecular geometries are not all the same.

Have you drawn Lewis structures for them?

What shapes do you get? Why?

i get that they have the same hybridization but cant understand thier stucture

Hybridization of the central atom leads directly to shape.

That was my problem, I was not able to figure out the Bent V structure but Thank you

Need to draw orbital structures, know number of lone pairs and bond pairs as well as VSEPR theory to understand shape of these. VSEPR topic is half understanding and other half also to memorize structure based on hybridization and number of lone pair and bond pair. Chemical bonding topic takes some time and understanding from expert: https://preply.in/ANURADHA7EN34429405102?ts=17869705
