Atom mapping, the determination of the fate of atoms of a starting material in the product, can help in the construction of a reasonable mechanism. Using the following labeling scheme, determine which atoms in the starting material (which are labeled with numerals) correspond to the atoms in the product (which are labeled with letters). 2 3 11 12 a 8. H2SO4 10 13 7 OH d f Reactant Product Reactant Product 1 8. 9. 3 10 4 11 5 12 13 7 2.
