Question

BlackTom AI · Accepted Answer

Question being examined asks which option would be classified as a strong bond.
Option 1: 'hydrogen bond' — Hydrogen bonds are indeed important for many biological structures, but they are relatively weak compared to covalent bonds. They occur due to dipole–dipole attractions between molecules or within a large molecule, not due to sharing electrons. So this option does not describe a 'strong bond' in the general sense of bond strength.
Option 2: 'none are strong' — This asserts that no bonds are strong, which is incorrect. In chemistry, covalent bonds are typically very strong intermolecularly within a molecule, certainly stronger than hydrogen bonds or van der Waals interactions. Therefore this statement mischaracterizes bond strength overall.
Option 3: 'covalent bond' — Covalent bonds involve sharing electron pairs between atoms and are typically the strongest type of intramolecular bond. They require substantial energy to break, which supports the idea that they are strong bonds in many contexts. This aligns with the standard understanding of bond strength.
Option 4: 'van der Waals interactions' — van der Waals forces (including London dispersion, dipole-dipole, and hydrogen bonding in some classifications) are relatively weak compared to covalent bonds and are generally considered secondary or auxiliary interactions rather than 'strong bonds' on their own. This makes this option incorrect when the criterion is strong bond.
Overall, evaluating the core idea of bond strength, covalent bonds stand out as the strongest typical intramolecular bonds among the options, whereas hydrogen bonds and van der Waals forces are notably weaker, and the statement that none are strong contradicts established chemistry.
