Show the net dipole moment (μ = 0 D) of the compounds a) CBr4
b) cis-1,2-Dibromoethene
c) trans:-1,2-Dibromoethene
d) 1,1-Dibromoethene

A

Explanation:

Using the equation above, the dipole moment is calculated to be 1.85 D by multiplying the distance between the oxygen and hydrogen atoms by the charge difference between them and then finding the components of each that point in the direction of the net dipole moment (the angle of the molecule is 104.5˚).
