Lesson 3: How does alkenes act?

Physical properties

- First 3 members are gases at r.t.p

Ø Made up of covalent molecules held by weak intermolecular forces

- All members are insoluble in water but soluble in organic solvent

Ø Like dissolve like

Chemical properties

- Similar for all alkenes

Ø Contains the same C=C covalent bond

- More reactive than alkanes

Ø One of the bonds in the C=C bond (pi bond) can break easily, allowing other atoms to join to the carbon atoms resulting in an addition reaction.
