Alkanes primarily produce carbon dioxide (CO2) and water (H2O) when they burn in the presence of oxygen. It is an exothermic reaction that releases heat and light energy.

Why alkane make good fuels?
Alkanes make good fuels because they have high energy content per unit mass, they undergo combustion reactions that release a large amount of heat energy when burned, and they are relatively abundant and easily obtainable from fossil fuel sources. Additionally, alkanes burn cleanly and produce less pollution compared to other fuel sources.
Why does flammability of alkenes decrease?
the flammability of alkanes decreases as the hydrocarbon chains increase in length their evapouration rates decrease as longer chained molecules have higher boling points so temperatures must be high for them to evaporate therefore there is no fumes or vapours for longer chained alkanes at room temp like nonane and so on these hydrocarbons need higher temp to produce vapours n therefore will not burn with just a match
Does combustion only happen to alkanes?
No, combustion can occur with any organic compound that contains carbon and hydrogen, not just alkanes. Combustion is a chemical reaction that involves the rapid oxidation of a material typically with the release of heat and light.
How do you produce such flame?
Burn hydrogen
What are alkanes?
Alkanes are a type of hydrocarbon compound made up of carbon and hydrogen atoms organized in straight or branched chains. They are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms. Alkanes are known for their relatively simple structure and are commonly found in petroleum products.

What is photoactivation of alkanes?
Photoactivation of alkanes is a process where alkanes are activated by irradiation with light, usually UV light, to produce reactive intermediates that can undergo further reactions. This process can lead to functionalization of alkanes, a typically unreactive class of compounds, enabling the introduction of new functional groups. Photoactivation of alkanes is a valuable tool in organic synthesis for generating complex molecules.
What are the hazards of alkanes?
If there is plenty of oxygen, the carbon gets converted completely to carbon dioxide and the hydrogen gets converted completely to water. This is complete combustion and the alkane would burn with a clean flame. If there is insufficient oxygen, there is incomplete combustion and some of the carbon does not get converted completely and ends up as soot. This results in a very smoky and sooty flame and is inefficient.
Which alkanes are liquid?
pentane and other alkanes above it
What come from crude oil alkanes or alkenes?
alkanes
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.
Does combustion only happen to alkanes?
No, combustion can occur with any organic compound that contains carbon and hydrogen, not just alkanes. Combustion is a chemical reaction that involves the rapid oxidation of a material typically with the release of heat and light.
Do alkanes contain phosphorus?
No, alkanes do not contain phosphorus. Alkanes are hydrocarbons composed of carbon and hydrogen atoms but do not contain phosphorus in their structure.
How do you produce such flame?
Burn hydrogen
Are longer chain alkanes more flammable than shorter chain alkanes?
Shorter chain alkanes are generally more flammable than longer chain alkanes. This is because shorter chain alkanes are more volatile and readily vaporize, making them easier to ignite. Longer chain alkanes are less volatile and require higher temperatures to vaporize and ignite.
