Physical Properties of Alkenes
(i) Alkenes are odourless and colourless.
(ii) These are soluble in organic solvents and insoluble in water.
(iii) Physical state
C1 -C4 → gas
C4 -C16 → liquid
> C17 → solid wax
(iv) B.P. and M.P. decreases with increasing branches in alkene.
(v) The melting points of cis isomers are lower than trans isomers because cis isomer is less symmetrical than trans. Thus trans bundles more hardly in the crystal lattice and hence has a higher melting point.
(vi) The boiling points of cis isomers are bigger than trans isomers because cis-alkenes has greater polarity (Dipole moment) than trans one.
(vii) These are lighter than water.
(viii) Dipole moment : Alkenes are weakly polar. The, Π-electron's of the double bond. May be simply polarized. Therefore, their dipole moments are greater than those of alkanes.
