- The dipole moment of bromobenzene is 5.17 × 10−30 C m and its polarizability volume is approximately 1.5 × 10−29 m3. Estimate its relative permittivity at 25 °C, when its mass density is 1491 kg m−3.plz explain step by step in detailI know that the answer to this question is 60, but I am struggling to understand why. Could somebody please draw this out for me 3-dimensionally or explain to me in detail why this is the case? One explanation I've heard is that it is because when the dihedral angle between the two methyl groups is 60, the molecular dipole moment between the two chlorine atoms is the smallest, therefore the answer is 60. This explanation is meaningless to me - that does not even seem to be what the question is asking. Is it a poorly-worded question? i need good explanation
