Answer
a) How many F atoms bonded to the central Xe atom? Four F atoms
b) Do all the atoms in XeF4 lie on a same plane?
Yes. All the atoms in XeF4 lie on a same plane, because the shape of XeF4 is square planar
c) A molecule with square planar geometry would result if two of the outer atoms were removed from an octahedral molecule. Does it matter which two of the outer atoms are removed?
Yes. If the two outer atoms are removed from an octahedral molecule, would result in square planar. But it depends on which outer atoms are removed and also depends on the lone pairs of the central atom.
d)If two adjacent outer atoms were removed from an octahedral molecule, the resulting geometry would most closely resemble a seesaw geometry.
e) Are all of the outer atoms geometrically equivalent in a square planar molecule or are there two types? Two types are there
f) what approximate angle at the Xe atom does an F atom make with an F atom that is adjacentt to it ? 90 degrees
