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

$(a)\; I < IV < II < III \\ (b)\;IV < I < II < III \\(c)\;IV < I < III < II \\(d)\;IV < II < I < III$

$O^{-},m^{-},P^{-}$ derivatives has $\alpha=60^{\circ},120^{\circ}$ and $180^{\circ}$ respectively , p-derivative has zero dipole moment.
Dipole moment of $m-$ chlorobenzene is more than foluene.
Hence b is the correct answer.
