Positive ions in a crystal repel each other
the VSEPR theory
The shape of chloromethane is tetrahedral.
Electron pairs
I don't know what "H'M" is supposed to be, so the question cannot be answered. Any binary compound is linear, because there's no other option; one doesn't really need VSEPR to predict that.
It has a linear shape
SiCl2Br2 would take a tetrahedral shape according to the VSEPR theory.
ClO3F would be tetrahedral.
A. The geometry it will have
Tetrahedral.
The position of bonding atoms is determined by electron pair repulsion.
Positive ions in a crystal repel each other
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
Electron pairs repelling each other push atoms apart.
How atoms are arranged in a molecule.
The VSEPR theory allows us to determine the molecular geometry of a molecule based on the number of electron pairs around the central atom. It helps predict the shape of molecules by minimizing electron pair repulsion. This theory is useful in understanding the spatial arrangement of atoms in molecules and their properties.
Because two atomic centres can only create a linear molecule.
