An ideal solution is formed when its components have identical intermolecular forces. This means that the molecules of the components in the solution have similar attractions and interactions with each other. When the intermolecular forces between the solute and solvent molecules are similar, they tend to mix uniformly and form a homogeneous solution.

Components of an ideal solution have identical intermolecular forces:
The intermolecular forces between molecules are responsible for the physical properties of a substance. In an ideal solution, the solute and solvent molecules have the same type of intermolecular forces, such as dipole-dipole interactions or London dispersion forces. This similarity in intermolecular forces allows the solute and solvent molecules to mix evenly and form a stable solution.

Components of an ideal solution do not show change in optical rotation:
Optical rotation is the rotation of the plane of polarized light as it passes through a chiral compound. In an ideal solution, the solute and solvent molecules do not have chiral centers or asymmetry, so they do not rotate the plane of polarized light. This means that there is no change in optical rotation when the components of an ideal solution are mixed together.

Components of an ideal solution do not show deviation from Raoult's law:
Raoult's law states that the partial pressure of a component in a solution is directly proportional to its mole fraction. In an ideal solution, the solute and solvent molecules do not have strong interactions or deviations from ideal behavior, so they adhere to Raoult's law. This means that the observed vapor pressure and composition of the solution can be predicted accurately using Raoult's law for ideal solutions.

Components of an ideal solution can be converted to an ideal gas:
An ideal gas is a theoretical gas composed of particles that do not interact with each other and occupy no volume. In an ideal solution, the solute and solvent molecules have similar intermolecular forces, which means that they do not strongly interact with each other. This similarity in intermolecular forces allows the components of an ideal solution to behave similarly to an ideal gas when they are converted to a gaseous state.

In summary, the correct answer is option D (Identical intermolecular forces) because components of an ideal solution have the same type of intermolecular forces, which allows them to mix uniformly, follow Raoult's law, and behave similarly to an ideal gas.
