Naming hydrocarbons.
« on: April 19, 2014, 03:08:30 PM »
I know how to name Alkanes, Alkenes, and Alkynes, but how do you name something that has both double and triple bonds?

It goes in the same way. A double bond get a lower number as a triplebond.

Something like hex-2,3-ene or 2,3hexene.

Why do you ask?

No it is called Hexa-2,3-diene.

I asked why you dont know how to name it correctly.

Oh! so you do use di- in this context. I was unsure about that. Thanks! Still seems a bit redundant, though.
And why 'hexa' not 'hex'? Is it just easier to say?

I'm not sure how to respond to your question - I don't know how to name it correctly because I haven't learned yet - That's why I'm asking.
