Answer to Problem 42P
C6 H5 -CH2 -COOH + NaBH4 / H2 O (No reaction.
Explanation of Solution
NaBH4 with water is a weak reducing agent therefore it cannot reduce the carboxylic acid and no reaction is observed with it.

- For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. དྲ。 ✗MgBr ?
