CHM 3120 Test #1 White Answers 1. Consider the following reaction: 7 Points O Base a) Identify the thermodynamic product O 1 b) Explain why this is the thermodynamic product (point form) Thermodynamic product formed at equilibrium Thermodynamic product is the most stable one Product with the most substituted double bond is most stable (3) c) Give reaction conditions that favor this product (point form) Base with similar pKa to substrate (alkoxide or NaH) protic solvent (alcohol) Excess substrate Avoid low temperature (3) 2. Draw structures for the unknown compounds. 8 Points . H N O HOAc C 10 H 20 N H 3 O+ C 8 H 14 O C 13 H 24 N Cl C 10 H 19 N K 2 CO 3 N 2 N 2 N 2 O 2 3. Draw reaction pathways to the possible products.
