Name these organic compounds: structure name H O CH3 CH3-CH2-OH CH, H Solution 1) Image is that of PROPANOIC ACID. remember the -COOH is a carboxylic acid group and the total number of carbons including that of the functional group is 3. Thus, the use of \"propane\". The suffix for carboxylic acids is \"oic acid\". Thus put together, propanoic acid. 2) Image is that of ETHANOL. Remember, -OH is an alcohol group, and the total number of carbon atoms are 2, thus the use of \"ethane\". The suffix for the alcoholic functional group is \"ol\". Thus, ethanol. 3) Image 3 is that of BUTANALDEHYDE. -CHO is the functional group called aldehydes. The total number of carbon atoms is 4 (including the carbon atom on the functional group). Thus, the use of butane. The suffix used for an aldehydic functional group is \"al\". Thus, the name butanaldehyde. .
