Chapters 1-11 1. Carbenes are diradicals and can have a transient existence during many reaction (particularly with alkenes). Isopropylene, :C(CH3)2, is a example of a carbone. The two electrons can share the same orbital or occupy two different orbitals. Provide the expecte hybridization when the two electrons are spin unpaired. For when they Draw the atomic orbitals of each and identify the valence orbitals on the carbene. H Hoe & H₂O 2. Account for the fact that the following carbocation...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
