When two ice cubes are passed over each other, they unite to form one cube. This is due to
Correct answer: A. H-bonding
- A. H-bonding
- B. Ionic bonding
- C. Covalent bonding
- D. Metallic bonding
Explanation
Two ice cubes can unite to form one cube when they are pressed against each other due to Hydrogen bonding. Hydrogen bonding is a type of intermolecular force that occurs between a hydrogen atom that is bonded to a highly electronegative atom (such as oxygen or nitrogen) and an atom that has a lone pair of electrons (such as oxygen). In the case of ice, the hydrogen atoms in the water molecules are bonded to the oxygen atoms, which are highly electronegative. This means that the hydrogen atoms have a partial positive charge, and the oxygen atoms have a partial negative charge. The oxygen atoms in two adjacent ice cubes can form hydrogen bonds with the hydrogen atoms in the other ice cube. These hydrogen bonds hold the two ice cubes together, forming a single cube.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
