Homework Help: Chemistry

Posted by Perry on Friday, July 3, 2009 at 6:53pm.

Hello!

I have a question that leaving me stumped. So E means opposite and Z means together. In order to do this alternate cis/trans arrangement you have to order molecules a priority either 1 and 2. You have to go along either side of double bond and determine priority. I'm so lost with these molecules.

here is what I came up with

First one is E
Second: don't know how to differientiate with one F and the Cl's
Third: don't know if this is even a E, Z
Fourth: Definitely Z
Sixth: Unsure between the F on one side and C on the other. Does this mean Z.

here are the molecules.
