Alkoxy carbonyl functional group is present in:
Correct answer: D. Ester
- A. Ether
- B. Aldehyde
- C. Carboxylic acid
- D. Ester
Explanation
The alkoxy carbonyl functional group is a defining feature of esters, which are characterized by the presence of a carbonyl group (C=O) bonded to an alkoxy group (-O-R). In this case, option D (Ester) is correct because it contains both components of the alkoxy carbonyl functional group. The other options do not fit the definition:Option A (Ether): Ethers lack the carbonyl group altogether and consist solely of an oxygen atom bonded to two hydrocarbon groups.Option B (Aldehyde): Aldehydes have a carbonyl group bonded to a hydrogen atom and do not have an alkoxy component.Option C (Carboxylic acid): While carboxylic acids contain a carbonyl, they also include a hydroxyl group, which is different from the alkoxy structure.Thus, the correct identification of the alkoxy carbonyl functional group is essential for recognizing that esters (option D) are the correct answer.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
