which has highest dipole moment
CCl4,CHCl3,CH2Cl2?
CHCl3 has Highest dipole moment.
Because CHCl3 is more polar than CH2Cl2 and CCl4.
In CH2Cl2the dipole moment of C-H and C-Cl bonds is min. Because the dipole moment is canceled due to the same side orientation of 2 H and 2Cl .
And CCl4 is non polar so dipole moment is zero here.
