What happens when alkanes burn in the air?
Alkanes can readily burn in the air. The reaction between Alkanes with excess Oxygen is called “combustion”. In this reaction, alkanes convert to Carbon dioxide (CO2) and water.
What's the difference between branched and unbranched alkanes?
Alkanes: The boiling point of unbranched alkanes smoothly increases as the number of Carbon atoms and the molecular weight are increasing. In general, branched alkanes have lower boiling points compared to the unbranched alkanes, having the same number of Carbon atoms.
How are alkenes used in the food industry?
Alkenes react with Hydrogen in the presence of a finely divided metal catalyst to form the corresponding alkane. The rate of the reaction is very low without a catalyst.
