Answer to Question #182069 in Organic Chemistry for Tharishini Ramachandran

Question

State the type of isomerism present in alkene with formula C4H8

Answer 1

Well, the formula C₄H₈

C4H8 specifies ONE degree of unsaturation; the SATURATED formula would be C₄H₁₀

C₄H₁₀ the which has TWO structural isomers

Now a degree of saturation specifies an olefinic bond OR a RING junction

So we got two alicyclic structural isomers, i.e. cyclobutane

cyclobutane, and methylcyclopropane

methylcyclopropane to start…

And we could recognize FOUR ACYCLIC OLEFINS: 1-butylene

1-butylene; Z-2-butylene

Z-2-butylene, E-2-butylene

E-2-butylene, and methylpropylene

methylpropylene.
