Answer 2

Do you know the rules for naming organic compounds?

First find the longest carbon chain that contains the C=C

You start numbering so that way the the C=C has the lowest numbers

If all the carbons are singled bonded to each other, the name would end in -ane

If there's one double bonded Carbon, then the name would end in -ene

If there's a triple bonded carbon, then the name would end in -yne

How long is the carbon chain?
If there's only two carbons, then it's ethane
three would make it propane
four would make it butane
five would be pentane
six would be hexane

and obviously the ane becomes ene or yne depending on if there's a double bonded or triple bonded carbon in the chain
