IUPAC name
« on: January 15, 2017, 12:26:09 PM »
What is the correct IUPAC name for the following structure:
CH2=CH-CH2-CH3


The way the professor has been teaching this, the name I came up with was

but-1-ene

but when entered into our homework post online, it was incorrect. I googled what but-1-ene would look like and the image that came up was the exact image on my homework. Someone help please?

For structure presented in the post above this is a correct IUPAC name. It may be abbreviated to butene.

Also sometimes called 1-butene. I was taught it your way, but I get the impression this is more popular these days.

But-1-ene is definitely the currently preferred IUPAC name.

1-Butene is also commonly used, I think this was the IUPAC name before the 1997 IUPAC Blue Book was published, but I'm not 100% sure on that.
My research: Google Scholar and Researchgate

1-butene seemed to be the answer my online assignment preferred. Thank you!
