# What geometric isomers are possible for "2-octene"?

Jul 15, 2017

Well, it's an olefin with a $C = C$ bond.......

#### Explanation:

And we could draw the molecular formula as.......

${H}_{3} \stackrel{1}{C} - \stackrel{2}{C} H = \stackrel{3}{C} H \stackrel{4}{C} {H}_{2} \stackrel{5}{C} {H}_{2} \stackrel{6}{C} {H}_{2} \stackrel{7}{C} {H}_{2} \stackrel{8}{C} {H}_{3}$

At $\stackrel{2}{C}$ we insert the olefinic bond, the so-called site of unsaturation. And we note that molecule would support geometric isomerism in that the double bond generates cis and trans isomers about ${C}_{2}$, ${C}_{3}$.

What would we call......

${H}_{2} \stackrel{1}{C} = \stackrel{2}{C} {H}_{2} \stackrel{3}{C} {H}_{2} \stackrel{4}{C} {H}_{2} \stackrel{5}{C} {H}_{2} \stackrel{6}{C} {H}_{2} \stackrel{7}{C} {H}_{2} \stackrel{8}{C} {H}_{3}$

Would this molecule be isomeric?
