Why would it only make one stereocenter? (b) In this example, we are not creating two new stereocenters. We are only creating one new stere-ocenter. So, the stereochemistry in this case becomes irrelevant. It is true that the reaction proceedsthrough an anti addition of OH and OH. However, with only one stereocenter in the product, thepreference for anti addition becomes irrelevant. We expect the following products, which are a pairof enantiomers:1) MCPBA2) H3O+OHOH+OHㅎ...OH (b)1) MCPBA2) H3O+
