question
complete the structure for butyl propanoate.

• use molecular formulas for substituents.

provide your answer below:

Explanation:

Step1: Analyze the ester structure

Esters have the general formula \(R - COO - R'\). For butyl propanoate, the "propanoate" part comes from propanoic acid (\(\text{CH}_3\text{CH}_2\text{COOH}\)), so the \(R\) group (the acyl part) is \(\text{CH}_3\text{CH}_2\text{CO}-\).

Step2: Identify the butyl group

The "butyl" part is a 4 - carbon alkyl group. The formula for the butyl group (\(R'\)) is \(\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3\) (n - butyl).

Step3: Combine the two parts

Combining the acyl part (\(\text{CH}_3\text{CH}_2\text{CO}-\)) and the butyl group (\(-\text{OCH}_2\text{CH}_2\text{CH}_2\text{CH}_3\)) gives the structure \(\text{CH}_3\text{CH}_2\text{COOCH}_2\text{CH}_2\text{CH}_2\text{CH}_3\).

Answer:

$$\text{CH}_3\text{CH}_2\text{COOCH}_2\text{CH}_2\text{CH}_2\text{CH}_3$$
