Functional Group -OH
The functional group -OH represents the hydroxyl group, which contains an oxygen atom bonded to a hydrogen atom. This functional group is characteristic of alcohols and carboxylic acids.
Identifying the compounds containing the functional group -OH:
A. Propane:
Propane is an alkane with the molecular formula C3H8. Alkanes are saturated hydrocarbons that do not contain any functional groups. Therefore, propane does not contain the functional group -OH.
B. Propanol:
Propanol is an alcohol with the molecular formula C3H7OH. The presence of the -OH group at the end of the molecule indicates that it contains the functional group -OH. Therefore, propanol contains the functional group -OH.
C. Ethanoic acid:
Ethanoic acid, also known as acetic acid, is a carboxylic acid with the molecular formula CH3COOH. Carboxylic acids contain the functional group -COOH, which consists of a carbonyl group (C=O) and a hydroxyl group (-OH). Therefore, ethanoic acid contains the functional group -OH.
D. Ethanol:
Ethanol is an alcohol with the molecular formula C2H5OH. Similar to propanol, it also contains the -OH group, indicating the presence of the functional group -OH. Therefore, ethanol contains the functional group -OH.
Conclusion:
Among the given compounds, propanol and ethanol both contain the functional group -OH. Therefore, the correct answer is option B and D.
