Which of the following is an example of a functional group in organic chemistry?
A
Helium atom (He)
B
Sodium ion (Na+)
C
Hydroxyl group (-OH)
D
Chloride ion (Cl-)
Verified step by step guidance
1
Understand that a functional group in organic chemistry is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Recognize that functional groups are typically composed of atoms such as oxygen, nitrogen, sulfur, or phosphorus, and are often attached to carbon atoms in organic molecules.
Identify the options given: Helium atom (He), Sodium ion (Na+), Hydroxyl group (-OH), and Chloride ion (Cl-).
Note that Helium (He) and Sodium ion (Na+) are not functional groups; they are an element and a cation, respectively, and do not participate in organic reactions as functional groups.
Recognize that the Hydroxyl group (-OH) is a common functional group in organic chemistry, found in alcohols, and is responsible for their characteristic reactions.
