Multiple Choice
Which of the following is a functional group commonly found in organic molecules?
A
Phosphate group
B
Hydroxyl group
C
Nitrogen group
D
Sulfate group
Verified step by step guidance
1
Identify the functional groups listed in the problem: Phosphate group, Hydroxyl group, Nitrogen group, and Sulfate group.
Understand that a functional group is a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Recall that the hydroxyl group is a common functional group in organic chemistry, represented by the formula \( \text{-OH} \). It is found in alcohols and is known for its ability to form hydrogen bonds, affecting the solubility and reactivity of molecules.
Consider the other groups: the phosphate group (\( \text{-PO}_4^{3-} \)) is more common in biochemistry, the nitrogen group is not a specific functional group, and the sulfate group (\( \text{-SO}_4^{2-} \)) is more common in inorganic chemistry.
Conclude that the hydroxyl group is the most common functional group among the options provided in the context of organic molecules.
