Question

Which of the following compounds has maximum dipole moment?
Options
A p-Dichlorobenzene
B m-Dichlorobenzene
C o-Dichlorobenzene
Correct Answer
D Carbon tetrachloride
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?
