Which of the following liquid pairs do not shows positive deviation from Raoult's law? — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

"Do not show positive deviation" means they show negative deviation or are ideal. Acetone-chloroform forms hydrogen bonds upon mixing (negative deviation). Water-nitric acid and water-hydrochloric acid interact strongly through ionization and hydrogen bonding (negative deviation). Benzene-methanol breaks existing hydrogen bonds in methanol, showing positive deviation. Therefore, correct answer is A,C,D.
