Question

When two ice cubes are pressed together, they join together. Identify the type of attraction which helps for the above process.
A. Vanderwaals
B. Covalent bond
C. Dative bond
D. Hydrogen bond

Answer 1

Hint: We know that the force of attraction that holds atoms, molecules or ions is termed as chemical bond. The four types of intermolecular forces are ionic bonds, hydrogen bonds, dipole dipole interaction and Vander Waal dispersion force.

Complete step by step answer:
Let’s discuss hydrogen bonds in detail. Hydrogen bond is a chemical bond in which formation of a covalent link of hydrogen atoms with other electronegative atoms, such as fluorine, nitrogen and oxygen atoms takes place in the same or another molecule.

Now, come to the question. The pressing of the two ice cubes results in the joining of the two ice cubes due to the formation of hydrogen bonds between water molecules. The hydrogen bonding can in water can be shown as follows:

One water molecule forms hydrogen bonds with four other water molecules, that is, intermolecular H-bonding. Due to this, the two ice cubes joined.

So, the correct answer is Option D.

Additional Information:
The order of strengths of four intermolecular forces is,
Ionic bonds>Hydrogen bond> dipole dipole interaction> Vander Waal dispersion force
Ionic bonding is the strongest force of attraction as this force is due to the attraction of positive and negative ions. Van Der Waals force is the weakest force of attraction.

Note: There are two types of hydrogen bonding, namely intermolecular H-bonding and intramolecular H-bonding. If the formation of hydrogen bonding takes place within the same molecule, then the type of H-bonding is intramolecular H-bonding. If the formation of H-bonding takes place between different molecules, then the type of H-bonding is intermolecular H-bonding.
