Physical Properties
Alkenes and alkynes are nonpolar compounds
•the only attractive forces between their molecules are dispersion
forces
Their physical properties are similar to those of alkanes
of similar carbon skeletons
•those that are liquid at room temperature are less dense than water (1.0 g/m
L)
•they dissolve in each other and in nonpolar organic solvents
•they are insoluble in water
