Answer

Mechanism of the reaction

Step by step solution

01

Lexan

Lexan is a polymer that consists of polycarbonates in its structure. This polymer can be prepared using the method of acid-catalyzed reaction between bisphenol A and diphenyl carbonate.

02

Meaning of acid catalysis

Acid catalysis is a chemical reaction that takes place in the presence of an acid which acts as a catalyst for the reaction. This type of chemical reaction is widely used in organic reactions.

03

Stepwise mechanism for the given reaction

The lone pair of electrons on the oxygen atom of diphenyl carbonate react with proton leading to the formation of a cation. Bisphenol A is added to this species. After rearrangements, the Lexan will be formed.

The stepwise mechanism is shown below.
