Solutions Weightage for JEE

149+ syllabus-aligned questions available

Quick answer

Solutions appears regularly in JEE Main and Advanced. Focus on high-frequency subtopics from Different methods for expressing the concentration of solution: molality, molarity, mole fraction, percentage (by volume and mass both), The vapour pressure of solutions and Raoult's Law - Ideal and non-ideal solutions, vapour pressure composition, plots for ideal and non-ideal solutions, Colligative properties of dilute solutions: a relative lowering of vapour pressure, depression of freezing point, the elevation of boiling point and osmotic pressure, Determination of molecular mass using colligative properties, abnormal value of molar mass, van't Hoff factor and its significance and pair revision with timed MCQs.

Prioritise high-return topics first. This weightage guide for Solutions helps you allocate revision time before JEE Chemistry papers.
