$NaCl$

Vedclass · Answer

(B) Acetone is a polar aprotic solvent with a moderate dielectric constant. Solubility in such solvents depends on the ionic character and lattice energy of the salt. $NaCl$ is a highly ionic compound with a very high lattice energy,making it essentially insoluble in organic solvents like acetone. $LiCl$ and $AgCl$ possess significant covalent character due to Fajan's rule (small cation size for $Li^+$ and polarizability of $Ag^+$),which increases their solubility in organic solvents compared to $NaCl$. $CCl_4$ is a non-polar covalent molecule and is miscible with acetone. Therefore,$NaCl$ is the least soluble among the ionic salts listed.
