CH₃COOCH₂(CH₂)₃CH₃

Here's how it breaks down:

* CH₃CO: This represents the acetyl group, which is the characteristic part of acetate esters.

* O: This is the oxygen atom connecting the acetyl group to the pentyl group.

* CH₂(CH₂)₃CH₃: This represents the pentyl group, which is a 5-carbon chain.
