Detailed explanation-1: -Due to the symmetric tetrahedral molecular geometry of CBr4, the individual C-Br dipole moments get canceled in opposite directions. In conclusion, CBr4 is a non-polar molecule with net µ =0.
Detailed explanation-2: -The CBr4 molecule is non-polar. The CH3Br molecule is polar. Both CBr4 and CH3Br have four regions of electrons around the central carbon atom. These are all bonding electron regions (clouds) so the shape of both molecules is tetrahedral.
Detailed explanation-3: -Methane $$( has symmetrical tetrahedral structure hence dipole moment is zero. Therefore it is non-polar.
Detailed explanation-4: -Tetrabromomethane, CBr4, also known as carbon tetrabromide, is an organic compound (carbon bromide). Both names are acceptable under IUPAC nomenclature.
