A weak electrical attraction between the positive end of one molecule and the negative end of another is known as?

• A. Ionic bond
• B. Covalent bond
• C. Hydrogen bond
• D. Metallic bond

Answer: (C)

Intermolecular forces arising from polar molecules show that the hydrogen bond is a special, relatively weak attraction where a hydrogen atom attached to a highly electronegative atom is drawn toward a lone pair on another electronegative atom. This fits the description of a weak electrical attraction between positive and negative ends of different molecules. Hydrogen bonds are stronger than most van der Waals interactions yet weaker than ionic or covalent bonds, and they play a crucial role in properties like water’s behavior and the structures of many biomolecules. The other bonds don’t fit because ionic bonds involve full electron transfer creating strong electrostatic attraction between ions, covalent bonds involve sharing electrons within a molecule, and metallic bonds involve a lattice of ions in a sea of delocalized electrons.
