Which of the following can be separated into its pure components by fractional distillation? — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Benzene ($C_6H_6$) and toluene (C7H8) form a nearly ideal binary liquid solution and do not form an azeotropic mixture at any composition. Therefore, they can be separated completely into pure components by fractional distillation. The other options form maximum or minimum boiling azeotropes and cannot be separated this way.
