4. (6) Select the alkenes that can show geometric isomerism (cis/trans isomerism): 1,6-dichloro-3-pentene 2-chloro-3-ethyl-3-pentene 4-bromo-3-methyl-3-octene 1,1-dichloro-2-methyl-1-hexene 4-fluoro-1-buttene 1,2-butendiene
6. (6) What stereochemistry are the alkenes in the molecule below? Select a correct answer for each alkene (i.e. you should select multiple answers as being correct). Je A A = trans E A=Z B=E B=Z C=E C=Z A = cis HO
