Question

complete the structure for methyl pentanoate.

• use molecular formulas for substituents.

provide your answer below:

Explanation:

Step1: Analyze the ester structure

Esters have the general formula \( \text{RCOOR}' \). In methyl pentanoate, the \( \text{R}' \) group (the alkyl group from the alcohol part) is methyl (\( \text{CH}_3 \)).

Step2: Determine the acyl part

The acyl part (\( \text{RCO}- \)) comes from pentanoic acid. Pentanoic acid has a 5 - carbon chain (\( \text{C}_4\text{H}_9\text{CO}- \) when considering the acyl group for ester formation).

Step3: Combine the parts

Combining the methyl (\( \text{CH}_3\text{O}- \)) from the alcohol (methanol) and the \( \text{C}_4\text{H}_9\text{CO}- \) from pentanoic acid gives the structure \( \text{CH}_3\text{OCOC}_4\text{H}_9 \).

Answer:

$$\text{CH}_3\text{OCOC}_4\text{H}_9$$
