The correct IUPAC name of the following structure CH3-CH2-CH=CH2 is But - 1 - ene
<h3>IUPAC rules for alkene nomenclature</h3>
- The parent alkene is chosen to have the longest carbon chain containing the carbon-carbon double bond.
- The alkane's suffix "ane" is changed to "ene."
- An alkene is referred to as a diene or triene depending on whether a double bond appears twice or three times in the parent chain.
- the location of side chains or double bonds denoted by the numbers 1, 2, 3, etc.
- The carbon atom in the double bond, which is written directly before the suffix "ene," receives the lowest number because it is the longest chain and is numbered from that end.
- If both sides of a double bond receive the same number as the chain is being numbered, the carbon chain is numbered so that the substituent receives the lowest number.
Hence the structure CH3-CH2-CH=CH2 is named on the basis of the above rule as but - 1 - ene.
