Vedclass · Answer

(B) The dipole moment depends on the vector sum of individual bond dipoles. $(I)$ $cis-1,2-difluoroethene$: The dipoles of $C-F$ bonds reinforce each other,resulting in a significant net dipole moment. $(II)$ $trans-1,2-difluoroethene$: The dipoles of the two $C-F$ bonds are in opposite directions and cancel each other out,resulting in a net dipole moment of $0$. $(III)$ $1-chloro-1,2,2-trifluoroethene$: The presence of three $F$ atoms and one $Cl$ atom creates a strong net dipole moment due to the high electronegativity of $F$. $(IV)$ $1,1-difluoroethene$: The two $C-F$ bond dipoles add up to give a net dipole moment. Comparing these,the order is $III > I > IV > II$. However,based on standard experimental values for these specific haloalkenes,the order is $I > IV > III > II$ (where $I$ is $cis-difluoroethene$,$IV$ is $1,1-difluoroethene$,$III$ is $trifluorochloroethene$,and $II$ is $trans-difluoroethene$). Thus,the correct option is $B$.
