Final answer:
The -OH group cannot exhibit an inductive effect. It does not have the necessary electronegativity to induce a change in electron distribution within a molecule.
Step-by-step explanation:
The statement that the -OH group cannot exhibit an inductive effect is true. The inductive effect is observed in organic molecules containing electronegative substituents, which can induce a change in the electron distribution within the molecule. However, the -OH group, which is a hydroxyl group, does not have the necessary electronegativity to exhibit inductive effects. Instead, it exhibits other types of chemical reactivity, such as acting as a leaving group in certain reactions.
