Chapter 17.3, Problem 17.12Q

(a)

Interpretation Introduction

Interpretation:

Using the condensed formula for palmitic acid, the mono, di and triglycerides structure have to drawn, through the esterification methods 

Concept Introduction:

Esterification reaction: Esters are prepared by the reaction of a carboxylic acid and an alcohol molecule with the elimination of water molecule.  The addition of a strong acid such as ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ is used to increase the rate of reaction.

Here, the $-OH$ group is attached to the carbonyl carbon atom of the carboxylic acid is being replaced by $-OR\text{'}$ the in the alcohol forming ester and water.

Addition Reaction:

• It is a type of reaction in which two reactants adding together to form a single product.
• It can be said as a reverse reaction of elimination reaction.
• It is a characteristic reaction of alkane.

Hydrogenation reaction is an addition reaction in which addition of hydrogen to an unsaturated molecule occurs

(b)

Interpretation Introduction

Interpretation:

Using the condensed formula for lauric acid, the mono, di and triglycerides structure have to be drawn, through the esterification methods 

Concept Introduction:

Refer to part (a).
