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...

Enol Enolates and Enamines: 
 
Enol Enolates: These are formed by deprotonating an alpha carbon adjacent to a carbonyl group in a molecule containing both a carbonyl and an enolizable proton. They are important intermediates in many organic reactions, particularly in aldol condensation and Claisen condensation reactions. 
 
Enamines: These are formed by the reaction of a secondary amine with a carbonyl compound, resulting in the formation of a carbon-nitrogen double bond. Enamines are versatile ...
