rakuenso Posted October 9, 2005 Share Posted October 9, 2005 What does this thing look like? When I draw it out I keep getting a carbon chain of >2... also, What does (Z) , (E) mean? different conformations? Link to comment Share on other sites More sharing options...
PuelloDiablo Posted October 12, 2005 Share Posted October 12, 2005 Well... first of all, I think you'd need it to be either in the cis or trans comformation to draw it. Secondly I think id' give it another name, because it's necessary to follow the longest carbon chain.. say 2,5-dimethyl-6-hexene. (z) or (e) means zuzammen or entgegen and is used to describe the conformation around a double bound if the are 3 or more groups around it. Normally you use cis-trans if there is are two groups and two hydrogen ions, but if there are more E-Z can be used to priotize the groups... can't remember the priority rules right now, but you can look it up in any textbook. The attached file shows trans-2,5-dimethyl-6-hexen (or trans-1,2-diisopropylethene) Link to comment Share on other sites More sharing options...
