3-Methylenepentane

Description:

3-Methylenepentane, with the CAS number 760-21-4, is an organic compound classified as an alkene due to the presence of a carbon-carbon double bond in its structure. It consists of a five-carbon chain with a double bond located between the third and fourth carbon atoms. This compound is characterized by its unsaturation, which contributes to its reactivity compared to saturated hydrocarbons. 3-Methylenepentane is typically a colorless liquid at room temperature and exhibits a distinctive hydrocarbon odor. Its molecular formula is C5H8, indicating it has eight hydrogen atoms for five carbon atoms, reflecting its unsaturated nature. The compound is soluble in organic solvents but has limited solubility in water. Due to the presence of the double bond, it can undergo various chemical reactions, including addition reactions, making it useful in organic synthesis. Safety precautions should be taken when handling this compound, as it may be flammable and potentially harmful if inhaled or ingested.
