Answer 3

Please answer ....
(a) Which conformational isomer of 1,2-difluoroethane does not have a dipole moment?

(b) 1,2-difluoroethene HFC=CFH has two stereoisomers. Which has the lower boiling point? Why?

1.cis-1,2-difluoroethene, because the Van der Waals interactions are greater.
2.cis-1,2-difluoroethene, because it does not have a dipole moment
3.trans-1,2-difluoroethene, because it does not have a dipole moment
4.trans-1,2-difluoroethene, because it has a dipole moment
