$o > m > p$

Vedclass · Answer

(A) The dipole moment $(\mu)$ depends on the vector sum of the individual bond dipoles.
For $o-$dichlorobenzene,the angle between the $C-Cl$ bonds is $60^{\circ}$,resulting in a large resultant dipole moment.
For $m-$dichlorobenzene,the angle is $120^{\circ}$,which gives a smaller resultant dipole moment.
For $p-$dichlorobenzene,the two $C-Cl$ bonds are in opposite directions $(180^{\circ})$,so their dipole moments cancel each other out,resulting in $\mu = 0$.
Thus,the correct order is $o > m > p$.

The order of dipole moment for $o-, p-,$ and $m-$dichlorobenzene is............
