Chapter 12, Problem 21Q

(a)

Interpretation Introduction

Interpretation:

Structural formula of the ester formed by the reaction between acetic acid and n-propanol has to be drawn.

Concept introduction:

Ester: One $-OR\text{'}$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOR\text{'}$.

Ester formation: 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 the $-OR\text{'}$ in the alcohol forming ester and water.

In chemistry, structure is the arrangement of chemical bonds between atoms in a molecule, specifically which atoms are chemically bonded to what other atoms with what kind of chemical bond.

In structural formula,

• ✓  All of the atoms are shown at each end and intersection of bonds.
• ✓  H atoms are shown

Explanation of Solution

Esters are prepared by the reaction of a carboxylic acid and an alcohol molecule with the elimination of water molecule.

Here, the carboxylic acid is,

Alcohol is,

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

In structural formula,

• ✓  All of the atoms are shown at each end and intersection of bonds.
• ✓  H atoms are shown

Therefore,

The structural formulas for the ester formed is,
