Similarly one may ask, what color is a clean flame?
Those bits of carbon get hot and glow, making the yellow light that you see. Once they cool a bit, those bits of carbon - and other unburnt stuff that isn't carbon dioxide or water vapor - also go into making smoke, which is why the clean, blue flames are smokeless, while the dirty, yellow flames come with smoke.
Additionally, what Colour flame is dangerous? The yellow colour comes from the soot particles produced by the flame. Yellow or red flames only burn at around 1,000 degrees C. This flame is dangerous as it produces more poisonous carbon monoxide gas.
Regarding this, why do alkanes burn with a clean flame?
Alkanes have less amount of carbon content in them..with sufficient oxygen all will burn cleanly. Alkanes general formula is CnH(2n+2). The higher the amount of carbon in a hydrocarbon,the more oxygen and more heat is required to convert all of the carbon to CO2. That's why alkanes generally burn with a clean flame.
Why do alcohols burn with a clean flame?
⚛ Alcohol combusts (burns) with a smokey or sooty flame due to the production of solid carbon. Combustion of alcohols releases energy making alcohols useful as fuels.
