... (ethanal) to form an enolate anion and a molecule of water. Step 2 The enolate anion attacks the carbonyl group of a second molecule of acetaldehyde. That intermediate is then protonated to form a beta-hydroxyaldehyde (3-hydroxybutanal). Step 3 The beta hydroxylaldehyde undergoes an elimination reac ...

Reaction Rate review questions
... Show that the sum of the two steps in the reaction mechanism is the same as the overall equation for the reaction. What is the rate-determining step? Explain. First step is the slowest so it is the rate determining step. Identify any intermediates or catalysts. F is an intermediate, no catalyst. Pre ...
