Methane, Ethane, propane, and butane are gas at room temperature.
The density of octane is higher than the density of pentane.
Octane can burn easier than butane in air.
The percentage of carbon of hexane is higher than that of pentane.
Isomers are compounds with the same molecular formula but different structural formulas.
Isomers do not necessarily share similar chemical properties unless they also have the same functional groups.
Combustion of butene produces more soot compare with combution of butane.
All alcohols are soluble in water.
The functional group of alcohol is the hydroxyl group.
Combustion of ethanol produces less soot compare with the combustion of ethane.
Owing to the presence of the hydroxyl group, the boiling point of alcohol is much higher than the alkane that has a similar molecular size.
Ethanol and propanol do not have any isomers.
