- Predict the products of the following biochemical reaction: CH2 CH-O + 3 KOH CH2-0 In particular, draw the structure of the product or products P in the drawing area below. If there are no products, because this reaction won't happen, check the No reaction box under the drawing area. Note: if there is more than one product, you can draw them in any arrangement you like. Also, just draw the structure of each product. You don't have to draw the complete right-hand side of the equation, including stoichiometric coefficients.
