Locate the double bond by the number of its first carbon. In this compound, the double bond begins at carbon #1, so the full name becomes: 1-butene. Note the INcorrect numbering in the second structure.
There is no such compound as 3-butene
.
Why the name 3-butene is incorrect?
The number at the beginning of the name indicates where the double bond originates.
The lowest possible number is used to number a feature in a molecule
; hence, calling the second molecule 3-butene would be incorrect.

Why does but-3-Ene not exist?
There is no But-3-ene
If we draw Butene with the double bond between the third and fourth Carbons, this is exactly the same structure as But-1-ene. Since the numbering of the Carbons goes from the end closest to the double bond the name But-3-ene is incorrect.
How do you name butenes?

. The word butene may refer to any of the individual compounds.
Is 3-butene possible?
There is no such compound as 3-butene
. 3. After the longest chain, containing the double bond is identified as the root name, number the carbons.
Is 3-Pentyne possible?
3-pentyne does not exist
. A carbon chain is numbered from the end that gives the triple bond the lowest number. The triple bond on third carbon atom is second from the opposite side and hence is named 2-pentyne.
