Textbook Question
Chapter 19, Problem 19.76QP
In a certain industrial process involving a heterogeneous catalyst, the volume of the catalyst (in the shape of a sphere) is 10.0 cm3. Calculate the surface area of the catalyst. If the sphere is broken down into eight smaller spheres, each having a volume of 1.25 cm3, what is the total surface area of the spheres? Which of the two geometric configurations of the catalyst is more effective? (The surface area of a sphere is 4πr2, where r is the radius of the sphere.) Based on your analysis here, explain why it is sometimes dangerous to work in grain elevators.

These are synthesis questions. You need to show how the starting material can be converted into
the product(s) shown. You may use any reactions we have learned. Show all the reagents you
need. Show each molecule synthesized along the way and be sure to pay attention to the
regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made
along the way, you need to draw both enantiomers and label the mixture as "racemic".
All of the carbon atoms of the products must come from the starting material!
