Final answer:
The classes of organic compounds that have functional groups with oxygen in them are aldehydes, ketones, carboxylic acids, esters, and ethers.
Step-by-step explanation:
The classes of organic compounds that have functional groups with oxygen in them are:
- Aldehydes: Aldehydes have the functional group -CHO. Some examples are formaldehyde (HCHO) and acetaldehyde (CH3CHO).
- Ketones: Ketones have the functional group >C=O. Examples include acetone (CH3COCH3) and 2-butanone (CH3COCH2CH3).
- Carboxylic acids: Carboxylic acids have the functional group -COOH. Examples include acetic acid (CH3COOH) and formic acid (HCOOH).
- Esters: Esters have the functional group -COO-. Some examples are ethyl acetate (CH3COOCH2CH3) and methyl salicylate (CH3OC6H4COOCH3).
- Ethers: Ethers have the functional group -O-. Examples include diethyl ether (CH3CH2OCH2CH3) and methyl tert-butyl ether (CH3OC(CH3)3).
