Identify the correct pairs of a mixture and their suitable separation techniques. — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

Iodine sublimes, leaving non-sublimable NaCl behind. Aniline is steam volatile and immiscible with water, so steam distillation is used. Benzene and toluene have a small boiling point difference and are separated by fractional distillation. Ortho/para nitrophenols are separated by steam distillation, not fractional crystallization.
