Provide reaction mechanisms for the following equations. (a) Eq. 23.17 (Hint: Refer to Sec. 11.5A, p. 524.) (b) Eq. 23.18 (Hint: Refer to Eqs. 22.101 and 22.102, p. 1157.) (c) Suggest a reason why the reaction in Eq. 23.18 stops after two additions, and a third doesnt occur in high yield. How might you change the reaction conditions to get a third addition?
Organic Chemistry, Dr. Peter Harrington Notes – Week 1 1-4 Carbon – essential element of o-chem Isotopes of Carbon- Carbon-12, most abundant: 98.9% Carbon-13, has one extra neutron: 1.1% # of protons and neutrons → 13 C # of protons → 6 Focus on the electrons, they are distributed in the space around the nucleus “Aufbau Principle” also can be thought of as the “building up” principle Spherical shells 1 2 3 4 Orbitals s p d f Orbitals: area in space where an electron is likely to be found Pauli Exclusion Principle: each orbital can contain only 2 electrons and they must be paired with opposite spin Hund’s Rule:
