False. Covalent bonds can be affected by chemical reactions. In a chemical reaction, covalent bonds can be broken, formed, or modified. This is because covalent bonds involve the sharing of electrons between atoms, and chemical reactions involve the rearrangement of electrons to form new bonds. During a chemical reaction, the atoms involved may gain or lose electrons, leading to the breaking or formation of covalent bonds. Therefore, covalent bonds can indeed be affected by chemical reactions.
