Explore advanced concepts in organic chemistry through this 49-minute lecture from Yale University's Freshman Organic Chemistry course. Delve into techniques for correcting orbital calculations to account for electron repulsion, including "Z-effective" and "Self Consistent Field" methods. Examine the concept of correlation energy and its role in orbital theory limitations. Investigate the Plum-Pudding model of atoms and its application to understanding molecular orbitals. Compare the molecular orbitals of CH4 and NH3 to the atomic orbitals of neon, analyzing how kinetic energy and nuclear positioning influence orbital shapes. Learn through case studies of methane and ammonia how moving nuclei distorts "electric puddings" in molecular structures.
