The Claisen condensation produces which of these? a) An ∝-keto ester b) A β-keto ester c) A β-hydroxy ester d) A β-hydroxyaldehyde e) A β-diketone Answer: B Topic: General Information Section: 19.2 Difficulty Level: Easy 2) Cyclization reactions, such as the Dieckmann condensation, are best carried out using fairly dilute solutions of the compound to be cyclized. Why is this so? a) It then is possible to use less base. b) The reagents generally are expensive. c) A smaller amo...

This chapter contains all necessary information needed to know about the alpha carbon chemistry of carbonyl compounds. These notes are color coded. It contains information about acidity, enolization, alpha halogenation, aldol and claisen condensation reactions, malonic and acetoacetic ester synthesis, conjugate addition and michael addition reactions. Reactions and mechanisms are shown clearly with arrows, and explanations as necessary.

1. If the delta G'° of the reaction A --> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from A to B. E For the reaction A --->B, delta G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol of B, 8 mmol of A. Which is the mo...
