Question

27 multiple answer 2 points which of the class of organic compound below contains a carbonyl group (-c=o) as a part of its structure? ether carboxylic acid ester aldehyde ketone aromatic previous next

Explanation:

Step1: Recall ether structure

Ether has -O- linkage, no -C=O.

Step2: Recall carboxylic - acid structure

Carboxylic acid has -COOH, contains -C=O.

Step3: Recall ester structure

Ester has -COO-, contains -C=O.

Step4: Recall aldehyde structure

Aldehyde has -CHO, contains -C=O.

Step5: Recall ketone structure

Ketone has -CO-, contains -C=O.

Step6: Recall aromatic structure

Aromatic compounds are based on benzene - like rings, no -C=O necessarily.

Answer:

B. carboxylic acid, C. ester, D. aldehyde, E. ketone
