Tetrahedral.
A^6
A. The geometry it will have
Because two atomic centres can only create a linear molecule.
It is tetrahedral.
Tetrahedral.
SiCl2Br2 would take a tetrahedral shape according to the VSEPR theory.

AX3
Tetrahedral
The shape of chloromethane is tetrahedral.
ClO3F would be tetrahedral.
CH4 has no lone pairs.It has 4 repulsive units.So shape is tetrahedral
Tetraedrical shape (pyraminoid)('Ball&stick' 3D-model is found in 'Related links')
Ax5
CCl4 shape is circular. This is determined by the Valence Shell Electron Pair Repulsion theory (VSEPR). The repulsion of the molecule determines the shape of it. CCl4 has a tetrahedral shape, owing to four bond pairs of electrons repelling each other to positions of maximum separation and minimum repulsion. The angle between bonds is 109.5 degrees.
The position of bonding atoms is determined by electron pair repulsion.
