Question: Draw the products formed in each oxidative cleavage.

Step-by-Step Solution

Verified

Answer

1Ozonolysis

Ozonolysis is the process by which ketones or aldehydes are formed. These can further be oxidized and reduced into other organic products. Organic acids are formed by the oxidation of aldehydes in this process.

2Explanation

a. The given compound is a substituted alkene that gives ketones after ozonolysis in the presence of (reducing agent).

The reaction is shown as:

Ozonolysis

b. The given compound is a substituted alkene that gives ketones after ozonolysis in the presence of zinc (reducing agent).

The reaction is shown as:

Ozonolysis

c. The given compound is a terminal alkyne that gives acid after ozonolysis in the presence of water.

The reaction is shown as:

Ozonolysis

d. The given compound is a substituted alkyne, which gives the corresponding acids after ozonolysis in the presence of water.

The reaction is shown as:

Ozonolysis
