Question

Complete the mechanism for the acid-catalyzed hydrolysis of the epoxide in alcohol by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows.

Answer 1

Concepts and reason

The three-membered cyclic ring containing 2 carbon atoms and 1 oxygen atom is represented as an epoxide. Epoxides are also known as cyclic ethers. The mechanism of the acid – catalyzed ring opening of an epoxide in alcohol can be completed by drawing curved arrows, lone – pair electrons, and charges.

Fundamentals

The reaction mechanism gives a step – by – step explanation of how the product arrives from the starting material. The movement of the electrons was indicated by curved arrows (double – headed arrows).

This type of arrow is called a double – headed arrow (curved arrow) which is used for the movement of electrons in the mechanism.

The lone-pair electrons and charges in the structure:
