6 Arrangethe following compounds in order of increasing dipole moment:Toluene () m-dichlorobenzene (I) o-dichlorobenzene (IIl) p -dichlorobenzene (Iv) |
|
Answer» Dipole moment of p – dichlorobenzene is zero because of symmetrical structure. o- and m-dichlorobenzene have higher dipole moments than toluene due to high electronegativity of chlorine than –CH3group. Further, to the o-dichlorobenzene has higher dipole moment due to lower bond angle than the m-isomer.so the answer is (b) |
