Determine the electron geometry (eg), molecular geometry (mg) and polarity of XeO3.?

Question

A) eg=tetrahedral, mg=trigonal pyramidal, polar

B) eg=trigonal planar, mg=trigonal pyramidal, polar

C) eg= trigonal planar, mg=trigonal planar, nonpolar

D) eg=trigonal bipyramidal, mg=trigonal planar, nonpolar

E) eg=octahedral, mg=tetrahedral, non polar

I think it should be D? Is this correct?

Answer 1

The correct answer is A. XeO3 has the same characteristics as NH3, including the unbonded electron pair in the central atom.

Answer 2

XeO3 has tetrahedral electron pair geometry, and trigonal pyramidal molecular geometry and it is polar.

The correct answer is (A).

The answer couldn't be (D).  Trigonal planar molecular geometry is not a subset of trigonal bipyramidal electron pair geometry.
