QUESTION:
For each alkene, indicate the direction of the dipole moment. For each pair, determine which compound has the larger dipole moment.
(a) cis-1,2-difluoroethene or trans-1,2-difluoroethene
(b) cis-1,2-dibromoethene or trans-2,3-dibromobut-2-ene
(c) cis-1,2-dibromo-1,2-dichloroethene or cis-1,2-dichloroethene
ANSWER:Step 1 of 3
(a) cis-1,2-difluoroethene or trans-1,2-difluoroethene
The direction of the dipole moment is shown below.
In cis-1,2-difluoroethene there is a net downward dipole moment. In trans-1,2-difluoroethene, the dipole moment are in opposite direction and they cancel each other,
Thus, cis-1,2-difluoroethene has highest dipole moment.
