Question

Draw the structure(s) of all of the alkene isomers, C H12, that contain an unbranched chain and that have EIZ isomers. • Consider E/Z stereochemistry of alkenes. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate structures with + signs from the drop-down menu. ChemDoodle

Answer 1

Cotiz The possible isomers are ) Нc = CH – CH2 - сн,- сна-сна 2) сня - сH = CH – CH2 – СН2-СН3 3) сH, — сн, - сн =CH– сна- сна ч нc= -е, -сH, -СН3 CH₃ сиз 5 сн, -d=cy —сн,-Сң, 6 CH3-CH -CH=CH-CH3 CH3

7) CH3 – CH – Chy – CH = CH Cala 8) CH₂=CH CH - CH₂ - CH₂ CH3 7) C1-CH=CH-CH2-CH3 Сн, (0) Ste Szchis CHR 10) HC сиз – CH = CH2 CH₂

Among the possible isomers Orly first three isomers are not branch. In that three isomers only and s 3rd isomer exhibit E-2 isomerism, .na lo HC A le CH2 - CH2 - CH3 C-C= CH₂-CH₂-CH₃ ztisomer E-isomer H H - CH₂-CH₃ 390 ų che NA H₂ C-HE Z-isomer isomer E-isomer'
