In the question posted in the photo, the dipole moment of one chlorine attached to benzene ring is 1.5D. So when 4 chlorines get attached, the top and bottom Chlorine’s dipole moments get cancelled and the remaining dipole moments of two chlorines produce a resultant in the downward direction. How is the magnitude of the resultant dipole moment of the two chlorine’s is also equal to 1.5D?? [ANSWER TO THE GIVEN QUESTION IS SAID AS 1.5D]
