Question 1 Report

An example of aliphatic unsaturated hydrocarbon is
Answer Details
An aliphatic unsaturated hydrocarbon is a hydrocarbon that does not contain any aromatic rings and has at least one double or triple bond between its carbon atoms. Pentane is an example of an aliphatic hydrocarbon, but it is not unsaturated, meaning it contains only single bonds between its carbon atoms. Butanol is also aliphatic, but it contains an -OH group and does not have any double or triple bonds. Propene, on the other hand, is an aliphatic unsaturated hydrocarbon because it has one double bond between its two carbon atoms. Finally, benzene is not aliphatic, but rather it is an aromatic hydrocarbon, which contains at least one aromatic ring with alternating double bonds. Therefore, the correct answer is "propene."
