To determine the functional group present in isoamyl acetate, we need to analyze the structure of the molecular formula given: [tex]\( CH_3CO_2CH_2CH_2CH(CH_3)_2 \)[/tex].
Let's break down the molecular structure step by step:
1. The molecular formula can be rearranged for better clarity into [tex]\( CH_3 - CO_2 - CH_2CH_2CH(CH_3)_2 \)[/tex].
2. Let's identify the different parts of the molecule:
- [tex]\( CH_3 - CO_2 \)[/tex]: This part suggests a part of the molecule with a dyad containing carbon and oxygen atoms.
- The [tex]\( CO_2 \)[/tex] group indicates the presence of two oxygen atoms adjacent to a carbon atom.
3. Recognize the functional group associated with [tex]\( CO_2 \)[/tex]:
- The structure [tex]\( RCOOR' \)[/tex] (where R and R' are carbon-containing groups) is characteristic of an ester. Specifically, [tex]\( CH_3 - CO_2 - R \)[/tex] implies one side of the ester (R group) represented by [tex]\( CH_3 \)[/tex] and another side (R' group) represented by [tex]\( CH_2CH_2CH(CH_3)_2 \)[/tex].
4. Confirm that this matches the criteria for an ester functional group:
- An ester has the general formula [tex]\( RCOOR' \)[/tex], where it contains two carbon atoms double bonded to one oxygen atom and a single bond to another oxygen atom.
From this analysis, we can conclude that the functional group present in isoamyl acetate is an ester.
Thus, the answer is:
ester
