* Polarity: NaCl is a highly polar ionic compound. The sodium (Na+) and chloride (Cl-) ions are strongly attracted to each other due to electrostatic forces.
* Diethyl ether is nonpolar: Diethyl ether is a nonpolar solvent. Its molecules are primarily held together by weak van der Waals forces.
"Like dissolves like" principle: This principle states that polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. Since NaCl is polar and diethyl ether is nonpolar, they are not compatible for dissolving.
Therefore, NaCl will not dissolve in diethyl ether to any significant extent.
