hey all..
why the dipole moment of chlorobenzene is lower than that of cyclohexyl chloride ???
Answers
Hence chlorobenzene is more electronegative than cyclohexyl chloride. Therefore, the density of electrons C-Cl bond at chlorine atom is less in chlorobenzene than cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride.

In chlorobenzene, the chlorine atom is attached to sp2chybridized carbon atom. In cyclohexyl chloride, the chlorine atom is attached to sp3 hybridized carbon atom. Hence chlorobenzene is more electronegative than cyclohexyl chloride. Therefore, the density of electrons C-Cl bond at chlorine atom is less in chlorobenzene than cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride.
