Question
Which of the following compounds has maximum dipole moment?
Correct Answer
Option C is the correct answer.
Detailed Explanation
o-Dichlorobenzene has the maximum dipole moment among the dichlorobenzenes because the C-Cl bond dipoles are at an angle (60°) and add constructively. p-Dichlorobenzene has zero dipole moment (dipoles cancel), and m-dichlorobenzene has a smaller dipole moment than ortho.
Hint
Which dichlorobenzene isomer has the largest dipole moment?
