Anything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral. Anything in an octahedral and a lone pair is the square pyramidal geometry. So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.

The electron geometry is tetrahedral when there are 4 electron groups around the central atom. This means the electron groups are arranged in a 3D shape resembling a pyramid with a triangular base.
Electron geometry for this is tetrahedral. There are two O-F single bonds, which makes 2 electron groups. There are two lone pairs around oxygen, which make up the last two electron groups. Molecules with four electron groups has a tetrahedral Electron geometry.

To determine the structural geometry of a molecule, structural pair geometry must be used. These are the amounts of pairs found surrounding a specific molecule, and they are unique to each type of atom.
The electron geometry of NCl3 is trigonal pyramidal (four electron groups around the central nitrogen atom). The molecular geometry of NCl3 is also trigonal pyramidal, as the three chlorine atoms and lone pair of electrons repel each other to form this shape.
trigonal planar
There are two electron groups around the central sulfur atom in H2S. This gives H2S a bent molecular geometry.
False. In geometry it is helpful to group objects and look at similarities between them.
