Question

Identify each of the following processes as hydrogenation, hydrolysis, or saponification and give the products:

a. the reaction of corn oil and hydrogen $\left({\mathrm{H}}_2\right)$with a nickel catalyst

b. the reaction of glyceryl tristearate with water in the presence of lipase enzyme

Short answer

Part (a) The reaction of corn oil with hydrogen $\left({\mathrm{H}}_2\right)$with a nickel catalyst is called as hydrogenation.

Part (b) Saturated fat is produced when fats such as glyceryl trilinoleate react with hydrogen in the presence of a nickel catalyst (all single bonds).

Step-by-step solution

Introduction.

The chemical reaction that occurs once molecular hydrogen interacts with another compound or element, typically in the presence of a catalyst such as nickel, palladium, or platinum, is known as hydrogenation.

When chemicals interact with water, they undergo hydrolysis, which results in the decomposition of both the substance and the water.

Saponification is the process by which a metallic salt of a fatty acid is formed.

Part (a) Step2: Given Information 

A nickel catalyst reacts with corn oil and hydrogen $\left(H_2\right)$.

To discover the procedure.

Part (a) Step 3: Explanation 

Hydrogenation is the way of integrating hydrogen molecules in to the multiple carbon-carbon bonds. As a result, saturated fats form.

During this time, a double bonds are transformed into single bonds, and the melting point gradually rises.

Part (b) Step 4: Given Information 

Glyceryl tristearate reacts with water due to the presence of lipase enzyme.

To discover the procedure.

Part (b) Step 5: Explanation 

Saturated fat is produced when fats such as glyceryl trilinoleate react with hydrogen in the presence of a nickel catalyst (all single bonds).
