Unformatted text preview: pecies Propylene: a linear 3- carbon π- system The allyl radical and ca0on can be considered in terms of orbitals. All carbons are sp2 (σ- framework) therefore each possesses a p- orbital available for π- bonding. H or H C H C C H H Developing the allyl π- MO diagram: 1.  Neglect the σ- framework; therefore, only need to consider the three carbon p- orbitals. 2.  Construct group orbitals (GOs). Group Orbitals Central Carbon 3.  Determine which GOs will interact with the central carbon atom p- orbital. 4.  Construct an MO energy level diagram for the π- system.
