Homework Help Overview

The discussion revolves around the naming of organic compounds that contain both double and triple bonds, specifically focusing on pentane and octane structures. Participants are exploring the conventions of nomenclature in organic chemistry.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to name compounds with specific structural features, questioning the correct order of naming based on functional groups and bond types. There is also a discussion about the priority of double versus triple bonds in nomenclature.

Discussion Status

The conversation is ongoing, with participants providing insights and suggestions regarding naming conventions. Some guidance has been offered about the correct endings for compounds with both double and triple bonds, but there is no explicit consensus on the names proposed.

Contextual Notes

Participants are working under the constraints of standard organic chemistry naming rules, and there is uncertainty regarding the correct application of these rules in specific examples. The original poster's attempts at naming are being critically evaluated.

organic chemistry help!

how do i name a pentane with a double bond on one end and triple bond on the other end?

pent-1-ene-4-yne?

if an octane has a double bond on one carbon and a phenyl group on another carbon . which should i start with first, the phenyl or the double bond?

Coumpounds with a double and triple bond take the ending -enyne, and the double bond receives lowest-numbering priority. Can you figure it out now?

Second question: name the phenyl first.

I think the secind one is x-phenyl-octene.I'm noit sure about the first,though.My first guess would be 4,1-methynpentene,but I'm not sure...

I do not think you are correct about the first one...let's let the OP take a shot at it. Keep the ending I mentioned earlier in mind.

The second one is correct except no dash b/w the two terms; should be x-phenyloctene, AFAIK.
