Chem 101 04/07/10 Calculate formal charge in a molecule based on Lewis structure Be able to define electro-negativity Understand and predict if molecules are polar (look in book) Be able to predict trends in bond order, bond length, Understand how molecules with double bonds can have isomers Be able to use the concept of hybridization to rationalize molecular structure Know the general features for molecular orbital theory Understand the differences Make sure to know EVERYTHING about the bonds and molecular structures Know pi and sigma bonds DO ALL PRACTICE PROBLEMS IN THE BOOK Hybrid Orbital These 2 degenerate orbitals would align themselves 180 degrees from each other This is consistent with the___ observed of beryllium compounds 2 degenerate sp orbitals (linear) 3 degenerate sp 2 orbitals (trigonal planar)
