Which of the following is a hazard associated with cyclohexene?

Cyclohexene is a colorless liquid hydrocarbon that is primarily known for its flammability. As an alkene, it has a double bond in its structure, which makes it reactive, particularly in combustion reactions. When mixed with air and exposed to ignition sources, cyclohexene can readily combust, leading to fire hazards in laboratory settings and during industrial handling.

Understanding its flammability is crucial for safe handling practices. Proper storage methods, such as keeping it in suitable containers away from heat sources, are essential to prevent potential fires. Additionally, the use of appropriate personal protective equipment (PPE) is advised when working with cyclohexene to minimize exposure to its vapors, which can also be irritating.

The aspect of cyclohexene being flammable highlights the importance of recognizing the physical properties of organic compounds, particularly those that are alkenes, and emphasizes the need for safety protocols in organic laboratory settings.
