Which of the following is an example of a simple organic molecule containing only one type of functional group?
A
Glycerol (C3H8O3)
B
Methanol (CH3OH)
C

D
Acetic acid (CH3COOH)
Verified step by step guidance1
Identify the functional groups present in each molecule. A functional group is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Examine Glycerol (C3H8O3): It contains three hydroxyl (OH) groups, which are the functional groups.
Examine Methanol (CH3OH): It contains one hydroxyl (OH) group, which is the only functional group present.
Examine Glucose (C6H12O6): It contains multiple hydroxyl (OH) groups and an aldehyde group, indicating more than one type of functional group.
Examine Acetic acid (CH3COOH): It contains a carboxyl group (COOH), which is a single type of functional group. However, the question asks for a simple organic molecule with only one type of functional group, and Methanol fits this description better as it has only one hydroxyl group.
