$CH_3Cl > CH_2Cl_2 > CHCl_3 > CCl_4$

Vedclass · Answer

(C) $CCl_4$ has a dipole moment of $0 \ D$ due to its symmetric tetrahedral geometry,where the bond dipoles cancel each other out.For the chloromethanes,the dipole moment depends on the vector sum of the $C-Cl$ bond dipoles.The experimental values are:$CH_3Cl = 1.86 \ D$$CH_2Cl_2 = 1.60 \ D$$CHCl_3 = 1.01 \ D$$CCl_4 = 0 \ D$Therefore,the correct order is $CH_3Cl > CH_2Cl_2 > CHCl_3 > CCl_4$.
