Arrange the following compounds in order of increasing dipole moment .
Toluene `(I)` m-dichlorobenzene `(II)`
o-dichlorobenzene `(III)` . P-dichlorobenzene `(IV)` .

A

I lt IV lt II lt III

B

IV lt I lt II lt III

C

IV lt I lt III lt II

D

IV lt II lt I lt III

Text Solution

Verified by Experts

The correct Answer is:
b

`mu_("res")=sqrt(mu_(1)^(2)+mu_(2)^(2) +2mu_(1)mu_(2)"cos"theta)`
Out of (II) and (III) 'O' isomer has more dipole moment
The increasing order of dipole moment is :
p-dichlorobenzene `lt` toluene `lt` m- dichlorobenzene `lt` o-dichlorobenzene

Polar covalent molecules exhibit dipole moment. Dipole moment is equal to the product of charge separation , q and the bond length d for the bond. Unit of dipole moment is debye. One debye is equal to 10^(-18) esu cm. Dipole moments is a vector quantity. It has both magnitude and direction. Hence, dipole moment of a molecule depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moment helps to predict the geometry of a molecules. Dipole moment values can be distinguish between cis- and trans- isomers, ortho, meta and pare-forms of a substance, etc. Q. Arrange the following compounds in increasing order of dipole moments, toluene (I), o-dichlorobenzene (II), m-dichlorobenzene (III) and p-dichlorobenzene (IV) :
