which type of bond represents a weak chemical bond?
The weak chemical bond being asked about here is the hydrogen bond.
Direct answer
In questions of the form “Which type of bond represents a weak chemical bond?” with options like hydrogen, ionic, covalent, or polar covalent, the expected correct choice is hydrogen bond.
Hydrogen bonds are much weaker than ionic or covalent bonds, and are often grouped with other weak interactions like van der Waals forces.
Mini breakdown: why hydrogen bonds are “weak”
- Hydrogen bonds form when a hydrogen atom that is covalently bonded to a very electronegative atom (like oxygen or nitrogen) is attracted to another electronegative atom nearby.
- They are intermolecular (between molecules) or sometimes between different parts of a large molecule (like DNA strands), so they’re easier to break than the strong bonds that hold atoms together in a molecule.
- By contrast, covalent , ionic , and polar covalent bonds are usually classified as strong bonds that hold atoms together within molecules or ionic lattices.
In many intro biology and chemistry quizzes, the exact question “Which type of bond represents a weak chemical bond?” has the keyed answer “hydrogen bond.”
Quick comparison table
| Bond type | Typical strength category | Where it acts | Example |
|---|---|---|---|
| Hydrogen bond | Weak | Between molecules or parts of large molecules | Between water molecules, between DNA base pairs | [10][5][8]
| Covalent bond | Strong | Within molecules (atom–atom) | O–H bonds inside a water molecule | [5][6][8]
| Ionic bond | Strong | Between oppositely charged ions | Na⁺ and Cl⁻ in table salt | [6][8][5]
| Van der Waals interaction | Very weak | Temporary attractions between molecules/atoms | Weak attractions in liquefied noble gases | [9][4][10]
TL;DR
- Which type of bond represents a weak chemical bond?
→ Hydrogen bond.
