Answer is: Molecule is tetrahedral.
CHBrClF (bromochlorofluoromethane) is a chemical compound with one of the simplest possible stable chiral compounds.
VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).
For bromochlorofluoromethane:
m = 4; the number of atoms bonded to the central atom.
n = 0; the number of lone pairs on the central atom.
