The principal reason for the extremely low solubility of NaCl in benzene (C₆H₆) is the _ . A) strong solvent- solvent interactions B) increased disorder due to mixing of solute and solvent C) hydrogen bonding in C₆H₆ D) strength of the covalent bond in NaCl E) weak solvation of Na⁺and Cl^-by C₆H₆

Question

Quizplus · Accepted Answer

The low solubility of NaCl in benzene is due to the weak solvation of Na+ and Cl- ions by benzene molecules (as mentioned in E). The lack of polar groups in benzene results in weak dipole-dipole interactions between benzene and ions, further decreasing the solubility of NaCl. Choices A, B, C, and D do not adequately explain the low solubility of NaCl in benzene.
