Use a sketch to show the change that occurs as a sulfur atombecomes a sulfide ion. Describe how the distance from the nucleusto the valence electrons changes as the sulfide ion forms and tellwhy this change occurs?
The carbanion then reacts with a molecule of acetone to give the product. Assuming the steady state approximation is valid, determine the concentration of the carbanion and derive a rate equation for the formation of product
