1. What is butadiene?
Butadiene is an olefin containing 4 carbon atoms and is an unsaturated compound in the hydrocarbon class. Because it contains two double bonds in its molecule, it has relatively special chemical properties. Butadiene can be used to prepare rubber, plastics, chemicals, etc.
2. What is the structural formula of butadiene?
The chemical formula of butadiene is C4H6, which can be represented by a molecular model. The structural formula of butadiene is CH2=CHCH=CH2, where "=" represents a double bond. In this structure, the butadiene molecule is connected by two adjacent cis double bonds, with two different single bonds in the middle.
3. What are the properties of butadiene?
Because the butadiene molecule contains two double bonds, it has some special properties different from saturated hydrocarbons. The molecule of butadiene is not linear, but presents a "Z"-shaped conformation. This asymmetric conformation makes it exhibit different properties in the reaction.
Butadiene can participate in a variety of organic reactions such as addition, oxidation, and rearrangement, the most important of which is the reaction with sulfides to prepare rubber. In addition, butadiene can gradually decompose under high temperature conditions to produce carbon black. Due to its unsaturated characteristics, butadiene is often used to prepare polymers with polymerizability.
IV. Conclusion
Butadiene is an olefin containing 4 carbon atoms, which has special properties different from saturated hydrocarbons in chemical reactions. Its structural formula is CH2=CHCH=CH2. It can be used in industry to prepare rubber, plastics, chemicals, etc.
