I am looking for some clarification on isomers of C4H8?
I am studying for an exam and was just browsing quiz questions on the internet and found a question on sparknotes asking to draw as many isomers of C4H8 as possible. In the solution section they came up with 5 possible isomers. I think I came up with an isomer that was not included in the solution section. I don't know the name so here is a description: 1 primary carbon-double bonded to-tertiary carbon.
