Question

Which one of the following liquid pairs will exhibit a positive deviation from Raoult's law? (A) n- hexane and n- heptane (B) ethanol and chloroform (C) phenol and aniline (D) chloroform and acetone

Tardigrade Admin · Accepted Answer

In case of positive deviation from Raoult's law A-B interactions are weaker than those between A-A or B-B. Water and ethanol, ethanol and chloroform, acetone and ethanol acetic acid and toluene etc. liquid pairs shows positive deviation from Raoult's law.

In case of positive deviation from Raoult's law $A - B$ interactions are weaker than those between $A - A$ or $B - B .$ Water and ethanol, ethanol and chloroform, acetone and ethanol acetic acid and toluene etc. liquid pairs shows positive deviation from Raoult's law.

In case of positive deviation from Raoult's law A−B interactions are weaker than those between A−A or B−B. Water and ethanol, ethanol and chloroform, acetone and ethanol acetic acid and toluene etc. liquid pairs shows positive deviation from Raoult's law.
