JEE Main levelSingle correct optionDifficulty 2 of 3sc123
Starch in water, sulphur sol and soap solution above its critical micelle concentration are classified, respectively, as
Amultimolecular, macromolecular and associated colloids
Bmacromolecular, multimolecular and associated colloids
Cassociated, multimolecular and macromolecular colloids
Dmacromolecular, associated and multimolecular colloids
Answer: B
Starch particles are single giant molecules, so the colloid is macromolecular. The sulphur sol particles are aggregates of many SX8 molecules, so it is multimolecular. Soap above the CMC forms micelles, which are associated colloids.
