CH2=CH-CH3 + H2 = CH3-CH2-CH3 (propan
CH2=CH2 + Cl2 (în CCl4) = CH2Cl-CH2Cl (1,2-dicloroetan)
CH2=CH-CH2-CH3 + H-OH = CH3-CH(OH)-CH2-CH3 (2-hidroxibutan/alcool sec-butilic/ 2-butanol/ butan-2-ol)
CH2=CH-CH3 + HCl (regula M) = CH3-CH(Cl) - CH3 (2-cloropropan)

masa molara propena = C3H6 = 2x13 + 6 = 36+ 6 = 42 g/mol
42g propena............36g C
4,2g propena............x g C
x= 3,6g C
