Discuss the physical properties of alkenes.
Asked by Topperlearning User | 01 Jun, 2016, 01:53: PM
Expert Answer
a) Physical State: At room temperature, alkenes with four or less than four carbon atoms exist in gaseous state. Alkenes with 5 to 17 carbon atoms generally exist in liquid state in room temperature. Alkenes with 18 carbon atoms and more are generally solids.
b) Solubility: Alkenes are insoluble in water but soluble in alcohol, ether and other organic solvents.
c) Alkenes are less dense than water and so they float on water.
d) Alkenes show geometrical isomerism due to the presence of carbon-carbon double bond.
e) Like alkanes, straight chain alkenes have higher boiling point than isomeric branched chain compounds.
