7.23 th e condensation reaction of acetone, (ch3)2co (propanone), in aqueous solution is catalyzed by bases, b, which react reversibly with acetone to form the carbanion c3h5o−. th e carbanion then reacts with a molecule of acetone to give the product. a simplifi ed version of the mechanism is (1) ah + b → bh+ + a− (2) a− + bh+ → ah + b (3) a− + ha → product where ah stands for acetone and a− its carbanion. use the steadystate approximation to fi nd the concentration of the carbanion and derive the rate equation for the formation of the product.
