Explanation:

To name an organic we follow certain rules.

1. Identifying the longest chain of carbon.

2. If any double/triple bond is present in the compound. The longest carbon is taken with the double/triple bond in the chain and not as a side group.

3. Naming of the compound is done as such that the double/triple bond gets the lowest number.

4. If the carbon chain is in form of a ring $cyclo -$ is added as a prefix.

• Now for naming, we start by counting carbons in the chain is counted. = 5 carbons
• When there is a double bond, we add $-ene$ to the carbon chain.

• Because there is only one double bond in this compound, we assign it the lowest possible numbering, namely 1.
• The chain is in the form of a ring, which we add. $cyclo -$ .

So the name of the compound, 1 cyclopentene.
