Verified Answer
Aqueous solution of a mixture contains LiCI, CuCI, NaCI and AICI3. Thi...
Polarising power of Li+ > Na+ and AI3+ > Na+
Thus, LiCI and AICI3 have covalent nature and extracted into ether.
CuCI due to d-electrons has covalent nature. (Polarising power of Cu+ > Na+).
Thus, only NaCI (ionic) remains in water.
Thus, LiCI and AICI3 have covalent nature and extracted into ether.
CuCI due to d-electrons has covalent nature. (Polarising power of Cu+ > Na+).
Thus, only NaCI (ionic) remains in water.

Understanding the Mixture in Aqueous Solution
The mixture of LiCl, CuCl, NaCl, and AlCl3 in an aqueous solution is subjected to shaking with ether. To determine what remains in the water, we need to consider the solubility and behavior of these compounds.
Solubility of Compounds
- LiCl and NaCl: Both lithium chloride (LiCl) and sodium chloride (NaCl) are highly soluble in water. They dissociate into their respective ions, making them remain in the aqueous phase.
- CuCl: Copper(I) chloride (CuCl) is less soluble in water. It does not dissociate significantly and tends to precipitate or remain as a solid when mixed with ether, thus leaving the aqueous phase.
- AlCl3: Aluminum chloride (AlCl3) is also highly soluble in water. It dissociates into Al^3+ and Cl^- ions, remaining in the aqueous phase.
Behavior of Ether
- Ether is a non-polar solvent and does not mix well with water. When the mixture is shaken with ether, the non-polar ether will extract non-polar or less polar compounds from the aqueous phase.
- CuCl, being less soluble and more non-polar compared to LiCl, NaCl, and AlCl3, is likely to be extracted into the ether phase or precipitate out.
Conclusion
After shaking the mixture with ether, the following remain in the aqueous solution:
- LiCl: Highly soluble, remains in water.
- NaCl: Also highly soluble, remains in water.
- AlCl3: Highly soluble, remains in water.
- CuCl: Less soluble, likely removed by ether.
Therefore, only NaCl remains in the aqueous phase after the reaction, leading to the correct answer being option 'D': Only NaCl.
