When 1,4-cyclohexadiene reacts with two equivalents of Br2, two separable compounds with different melting points are formed. Account for this observation.
Hybridization of Atomic Orbitals Linus Pauling 1935 Hybridization (combined) Atomic Orbitals different atomic orbitals can combine to give new hybrid orbitals These hybrid orbitals reflect the geometry of the molecule The problem comes from not knowing which molecules hybridize and which ones don’t Predicting Hybridization of Atomic Orbitals Difficult to predict Rules 1. Determine the geometry of the regions of high electron density 2. Assign the set of hybridized orbitals that corresponds to the geometry Sp linear, 180° 2 Sp trigonal, 120° 3 Sp tetrahedral, 109.5° 3 Sp d trigonal bipyramidal, 120°, 90° 3 2 Sp d octahedral, 90° Only three possible hybridization modes for Carbon Sp, Sp , Sp2 3 Geometry of Hybridization of Orbitals
