For a given molecule, it electronic geometry equivalent to molecular geometry?
It can be, though sometimes it is the same as the molecular geometry.
I will try to illustrate with 2 examples: (i) the water molecule; and (ii) the methane molecule,
On the other hand, around the oxygen atom in the water molecular there are also 8 electrons: 4 in the
However, because we describe molecular geometry on the basis of atoms, and not on lone pairs, we describe the geometry of the water molecule as bent. To a second approximation we would predict that the lone pairs would compress the
If you have any queries or objections, please ask me to clarify. This is a fairly fundamental aspect of bonding and structure to get your head around.
