What if different compounds have four electron clouds (same electron cloud geometry), but different molecular geometries. Explain.?

Think about the compounds CH4, NH3, H2O and HF. The main atom in each of these compounds has 4 pairs of electrons arranged around it in a (roughly) tetrahedral arrangement. When you talk about the shape of the molecule, you are describing the positions of the atoms. So, the molecular geometries of these four compounds are:
CH4 - Tetrahedral
NH3 - Trigonal pyramid
H2O - Bent
HF - Linear

Then some of the electron clouds are non-bonding. CH4, NH3, H2O all have 4 electron clouds around the central atom, but they have different molecular structures due to what's at the end of each cloud.
CH4 ---> 4 atoms at ends of clouds
NH3 ---> 3 atoms at end, one NB pair
H2O ---> 2 atoms at end, two NB pair
All have same electron geometry, ut different molecular structures.
