why do saturared compounds burn with blue flame
Answers
This happens because of incomplete combustion of the saturated hydrocarbon in the air. As a result, the bottom of the cooking utensils gets blackened from the outside. Unsaturated hydrocarbons like ethyne, also known as acetylene, burn to produce a yellow, sooty flame due to incomplete combustion in air.mark me as brainlist
Answer:
When saturated hydrocarbons burn, they produce a blue, non-sooty flame.
Let’s study this with the help of an example.
Liquefied petroleum gas, also known as LPG, is a fuel used for cooking.
LPG mainly contains butane, along with small amounts of propane.
Let’s observe the Bunsen burner.
It has air holes near its base, which can be opened or closed with the help of a sliding valve.
Let us first keep the air holes fully open and light the burner.
On burning LPG in air, the propane and butane in it react with the molecular oxygen to form carbon dioxide and water vapour, besides releasing heat and light.
We see that the gas burns with a blue, non-sooty flame and does not give out black smoke.
