Physical Properties

The melting and boiling points of alkenes are determined by the regularity of the packing, or the closeness, of these molecules. Alkene isomers that can achieve more regular packing have higher melting and boiling points than molecules with the same molecular formula but weaker dispersion forces. Alkenes are non-polar, and they are both immiscible in water and less dense than water. They are generally soluble in organic solvents. In addition, they do not conduct electricity.
