Hello!
I'm having problem deciding which alternative is the correct one.
CH2-CH3

CH2≈C-C≈CH2

CH2-CH2-CH3
I know the rules of naming carbon chains
but I got confused of this one. Should i conclude both double bonds to call it ....buta-1,3-diene or name the 2nd double bond methyl ....hexene? The 2nd suggestion sounds wrong but I would like to get a good explanation if possible.
