Solution

Solution Steps

Step 1: Understanding the Alkene Naming Convention

In organic chemistry, alkenes are hydrocarbons that contain at least one carbon-carbon double bond. The base name of an alkene is derived from the longest continuous chain of carbon atoms that includes the double bond. The suffix "-ene" is used to indicate the presence of a double bond.

Step 2: Identifying the Longest Carbon Chain

To determine the base name of the alkene, identify the longest continuous chain of carbon atoms that includes the double bond. This chain will determine the root name of the alkene.

Step 3: Numbering the Carbon Chain

Number the carbon chain starting from the end closest to the double bond. The position of the double bond is indicated by the number of the first carbon atom involved in the double bond. This number is used as a prefix to the base name.

Final Answer

The base name of the alkene chain is determined by the number of carbon atoms in the longest chain that includes the double bond, and the position of the double bond. For example, if the longest chain has 5 carbon atoms and the double bond starts at the first carbon, the base name would be "pent-1-ene".

\(\boxed{\text{Base name of the alkene chain is determined by the number of carbons and position of the double bond.}}\)
