Which of the following is a common functional group found in organic molecules?
A
Hydroxyl group (-OH)
B
Sulfate group (-SO4)
C
Phosphate group (-PO4)
D
Nitrite group (-NO2)
Verified step by step guidance
1
Identify the functional groups listed in the problem: Hydroxyl group (-OH), Sulfate group (-SO4), Phosphate group (-PO4), and Nitrite group (-NO2).
Understand the definition of a functional group: A functional group is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Recognize common functional groups in organic chemistry: Hydroxyl groups (-OH) are commonly found in alcohols and are a key feature in organic molecules.
Compare the listed functional groups: Hydroxyl groups are more prevalent in organic chemistry compared to Sulfate, Phosphate, and Nitrite groups, which are less common in typical organic molecules.
Conclude that the Hydroxyl group (-OH) is the most common functional group found in organic molecules among the options provided.
