Class 12 Chemistry — Solutions Important Questions with Answers (Long answers)
Class 12 Chemistry board is physical (colligative, EMF, rate), inorganic (d-block, coordination) and a long organic run from haloalkanes to biomolecules. This hub follows the rationalized ten-chapter shape. “Electrochemistry class 12 important questions” and “aldehydes ketones MCQ” open hidden-answer practice, twenty items a page, no leaked-paper talk.
Molarity, molality, mole fraction, Henry, Raoult, and colligative (ΔTb, ΔTf, π). Van’t Hoff i for electrolytes. A non-volatile solute lowers vapour pressure. Ideal versus non-ideal is the enthalpy/volume story. Write the formula the question named — molality is not molarity. You are on Solutions (Long answers), page 1 of 1 — 1 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
