A sooty flame is yellow and produces soot or carbon due to incomplete combustion of fuel. A non-sooty flame is blue and indicates complete combustion, where fuel is completely burnt. The presence of soot in a flame is caused by insufficient oxygen supply or improper fuel-air mixture in the combustion process.
A "sooty flame" indicates that incomplete combustion is taking place. The most likely cause for incomplete combustion is lack of oxygen.

How do you change the type of Bunsen burner flame?
To change the type of Bunsen burner flame, adjust the air hole at the base of the burner. Closing the air hole will produce a yellow, sooty flame (reducing flame) while opening it will create a blue, non-sooty flame (oxidizing flame).
Why does benzene burn with sooty flame?
Benzene burns with a sooty flame because it is a hydrocarbon that undergoes incomplete combustion. This results in the production of carbon particles, or soot, along with other byproducts like carbon monoxide and unburned hydrocarbons.
What organic compound is flammable and will burn with a sooty flame?
Hydrocarbons like alkanes (e.g. propane, butane) are organic compounds that can burn with a sooty flame due to incomplete combustion, which produces carbon particles.
Why benzene burns with sooty flame why not hexane?
Benzene burns with a sooty flame due to its incomplete combustion, which results in the formation of carbon particles (soot). Hexane, on the other hand, is a saturated hydrocarbon and tends to undergo complete combustion, resulting in a cleaner flame with less soot formation.
Why chloroform give sooty flame?
Chloroform contains carbon atoms which form soot when incompletely combusted. When chloroform is burned, the carbon atoms do not fully combine with oxygen, resulting in the production of soot particles that create a sooty flame.
Is sooty flame a luminous or non luminous?
A sooty flame is typically considered a non-luminous flame because it does not produce significant visible light. It appears dark or dim due to the presence of unburned carbon particles (soot) in the flame.
What are elements when hydrocarbon burns?
When a hydrocarbon is burnt in the presenceof oxygen it gives heat, light, and carbon dioxide gas producing a sooty or non-sooty flame
How do you change the type of Bunsen burner flame?
To change the type of Bunsen burner flame, adjust the air hole at the base of the burner. Closing the air hole will produce a yellow, sooty flame (reducing flame) while opening it will create a blue, non-sooty flame (oxidizing flame).
What is a sooty flame in Hindi?
A sooty flame in Hindi is called "ā¤ā¤žā¤˛ā¤ž ā¤§āĨā¤ā¤ā¤Ļā¤žā¤° ā¤āĨā¤ĩā¤žā¤˛ā¤ž" (kala dhuanadar jwala).
What are used to identify substances?
odour,melting/boling point,solubility in water,sooty or non- sooty flame on combusion,sodium fusion test,colour on adding KMnO4..
Is a sooty flame contains gases and tiny solid particles?
yes

What are the advantages and disadvantages of each type of flame of the Bunsen burner?
It is less hotter than non luminous flame. Used for lighting only It produces soot that makes apparatus sooty
When air hole of the Bunsen burner is closed what is the observation?
When the air hole of a Bunsen burner is closed, the flame will be yellow and sooty. This occurs because without sufficient air supply, incomplete combustion of the gas produces a sooty flame.
