Per NCERT, when distilling a mixture of ACETONE (boiling point ~56 °C) and WATER (boiling point 100 °C), which liquid is collected first in the receiver?
ABoth collected together at the same time
BWater — heavier liquid collected first
CNeither — only solids are obtained
DAcetone — the lower-boiling liquid vaporises first, is condensed, and collected first
Answer & Solution
Correct answer: D. Acetone — the lower-boiling liquid vaporises first, is condensed, and collected first
Per NCERT, in distillation the lower-boiling liquid is vaporised + condensed first. Acetone (56 °C) boils before water (100 °C), so it's collected first.
