Download Solution PDFThe correct answer is yellow.Key Points
- When unsaturated hydrocarbons burn, they produce a yellow flame due to the presence of carbon particles in the flame.
- Unsaturated hydrocarbons are hydrocarbons that contain at least one double or triple bond between carbon atoms in their molecular structure.
- Some examples of unsaturated hydrocarbons include alkenes and alkynes.
Additional Information
- Blue is the color of the flame when alkanes, which are saturated hydrocarbons, burn.
- This is because alkanes do not contain double or triple bonds and produce a complete combustion reaction.
- Red and green flames are typically produced by burning metals or metal salts.
- It is important to note that the color of the flame produced by burning hydrocarbons can also be affected by other factors, such as the presence of impurities or the amount of oxygen available for combustion.
