Explanation (300 words):

3-Methylcyclopentene is an organic compound that belongs to the family of alkenes, specifically cycloalkenes because it has a ring structure with a carbon-carbon double bond. The base structure is cyclopentene, a five-membered carbon ring with one double bond. In this molecule, a methyl group (–CH₃) is attached to the third carbon of the ring.

Let’s break the name down:

• “Cyclopentene”: This tells us the main structure is a five-membered ring (cyclopent-) containing a double bond (-ene). The double bond is assumed to be between carbon 1 and carbon 2 unless otherwise specified.
• “3-Methyl”: This indicates a methyl group (–CH₃) is attached to carbon 3 of the cyclopentene ring.

To draw or understand the structure, we follow these steps:

1. Draw a pentagon to represent the cyclopentane ring.
2. Add a double bond between carbon 1 and carbon 2 to make it cyclopentene.
3. Number the ring starting at one end of the double bond to give the double bond the lowest possible numbers. So, the double bond is between carbon 1 and carbon 2.
4. Place a methyl group on carbon 3.

The final structure features a five-membered ring with a double bond between C1 and C2, and a methyl group branching off C3. This type of compound may be used in organic synthesis and is important in understanding concepts of ring strain, substitution, and isomerism in alkenes.
