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?
Answer Alkanes are saturated hydrocarbons having a general formula CnH2n+2. Alkanes are unreactive comparing to alkenes, they are not affected by acids or alkalies. But they burn well in a good supply of oxygen, forming carbon dioxide and water vapour. giving out plenty of heat.

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.
Can graphite burn and produce flames?
Yes, graphite can burn and produce flames when exposed to a high enough temperature.
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.
How do you produce such flame?
Burn hydrogen
Do alkanes contain phosphorus?
No. alkanes contain only hydrogen and carbon.
Can oil burn in a controlled manner to produce heat and energy?
Yes, oil can burn in a controlled manner to produce heat and energy.
