i don't understand how isomers could arise from positioning of carbon-carbon multiple bonds.
So isomers with double bonds are stereoisomers. They arise because rotation of the carbon atoms with the double bond is restricted. So if you use the example of but-2-ene you can see that the difference between the two isomers of CH3CHCHC3 is the arrangement of the atoms around the C=C
Hope this helps, and if there's anything else feel free to ask
