Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.

Question

For which reaction mechanisms—S_N1, S_N2, E1, or E2—of the
following statement true? A statement may be true for one or more
mechanisms.

Racemization at a stereogenic center occurs.

Expert Solution

Step 1

The S_N1 reaction proceeds follows a two step mechanism in which the first step is the formation of carbocation by the removal of leaving group. Then the previously formed carbocation is attacked by nucleophile followed by deprotonation to give the corresponding product.

General mechanism of the reaction is as follows:
