Can anyone please explain to me why this molecule is named as such (IUPAC)? I've looked at it myself and have come up with different answers, such as a lower number for the double bond, and changing "methylethyl" to isopropyl. Name is: 1-methyl- 4-(1-methylethyl)- 2,3-dioxabicyclo[2.2.2]oct- 5-ene

Classes that require you to learn nomenclature are shit; nobody cares, it's obsolete. Tell your prof to go fuck himself, because he's being lazy by wasting your time with this shit.

Isopropyl will (always?) be 1-methylethyl in IUPAC..

I guess you would start with the ring.

Where does numbering start: well, it's either near the isopropyl (excuse me, 1-methylethyl) or the methyl.

I think you go alphabetically here? So methyl > 1-methylethyl.

Then you just have to figure out how to name the ring. Apparently, it counts as 8 "carbons" but the 2,3 are oxygen. So, yeah, no clue how to name that fucker, and
I wouldn't know where to start if you didn't give me the name.

My god, just call it fucking ascaridole, I don't know how to do this shit anymore.
