Hybrid Orbitals Bonding in Complex Molecules

Solved Exercise 1-14 Working with the Concepts Orbital Splitting Diagrams [Pg.31]

Construct a molecular-orbital and energy-spUtting diagram of the bonding in He2. Is it favorable [Pg.31]

Contrary to Really the perception of the periodic table encompassing all matter, the elements and their compounds represent only a small and visible fraction of the universe 4.6% The nature of the remainder— dark energy (72%) and dark matter (23%)— is not well understood. In the (for us tangible) 4.6%, hydrogen is the most abundant element (75%), followed by helium (23%), oxygen (1%), and then carbon (0.5%). [Pg.31]

Let us now use quantum mechanics to construct bonding schanes for more complex molecules. How can we use atomic orbitals to build linear (as in BeH2 , trigonal (as in BH3), and tetrahedral molecules (as in CH4) (See Lewis structures in margin). [Pg.31]

Consider the molecule beryllium hydride, BeH2. Beryllium has two electrons in the 1 orbital and two electrons in the 2s orbital. Without unpaired electrons, this arrangement does not appear to allow for bonding. However, it takes a relatively small amount of energy [Pg.31]
