Verified step by step guidance

Identify the role of functional groups in organic chemistry. Functional groups are specific groups of atoms within molecules that have characteristic properties and chemical reactivity.

Understand that functional groups are crucial in determining the chemical reactivity of organic molecules. They are the sites of chemical reactions and influence how molecules interact with each other.

Recognize that functional groups affect the physical properties of organic molecules, such as solubility and boiling point. For example, hydroxyl groups (-OH) can form hydrogen bonds, increasing solubility in water.

Consider the statement about molecular weight. Functional groups themselves do not determine the molecular weight; rather, they contribute to the overall structure and properties of the molecule.

Evaluate the given statements: The correct statement is that functional groups are responsible for the chemical reactivity and properties of organic molecules, as they define how molecules behave in chemical reactions and influence their physical properties.
