Brainly User Brainly User The dipole moment of 1,4-dichlorobenzene, C6H4Cl2, is zero, but 1,4-dihydroxybenzene, C6H4(OH)2, exhibits a net dipole moment. Therefore, the dipole moment of benzene and substituted molecules are calculated by different theoretical or experimental calculation formulas in chemistry. 1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDB or para) is an organic compound with the formula C 6 H 4 Cl 2.This colorless solid has a strong odor.The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring.. The 1,4-isomer is most symmetrical. This paper (J. Sep. Sci. The in vitro interaction of 1,4-dibromobenzene with calf thymus DNA was mediated mainly by microsomes, especially those from liver of both species and from mouse lung. Thus, dipole moment: C-Cl >>> C-H. Mouse subcellular fractions were more active then rat subcellular fractions. From this answer, I came to know that 1,4-diiodobenzene has a dipole moment of $0.19~\rm D$ in benzene at $20\ ^\circ\rm C$. Both cytochrome p450 and glutathione-transferases are involved in 1,4-dibromobenzene bioactivation. Along with the dipole moment the length of the dipole is shown. Thus, the dipole moment of C-Cl is approximately the same as that of CH 3 Cl. CONTROLS . Just google. 1,3 is also polar, but 1,4 is not, because of the vector cancellation of the C-Cl bond dipoles.
