Question

Tick (✔) the most appropriate answer.

The intermolecular spaces between the particles are minimum in the case of:

• A. Wood
• B. Water
• C. Iron
• D. Carbon dioxide

Answer 1

The correct option is C

Iron

The explanation for the correct option:

(C) Iron

• Solids have the highest inter-molecular forces of attraction with respect to liquids & solids.
• Although wood & iron both are solids in the case of iron, the cohesive forces(inter-molecular forces of attraction within the same substance) are stronger than that of wood particles.
• Therefore, Iron molecules have the least inter-molecular spaces in comparison with other given options.

The explanation for the incorrect options:

(A) Wood

• In this case, the cohesive forces are comparatively lesser than that of Iron particles.

(B) Water

(D) Carbon dioxide

• More the inter-molecular forces of attraction, lesser will be the inter-molecular spaces in the following order: Gases > Liquids > Solids
• That is, inter-molecular spaces for Carbon dioxide(gas) > Water(liquid).

Thus, option(C) is correct. The intermolecular spaces between the particles are minimum in the case of Iron.
