From the figure of column chromatography given below, identify incorrect statements. A . Compound ‘ c ’ is more polar than ‘ a ’ and ‘ b ’ B . Compound ‘ a ’ is least polar C . Compound ‘ b ’ comes out of the column before ‘ c ’ and after ‘ a ’ D . Compound ‘ a ’ spends more time in the column Choose the correct answer fro

Step-by-step solution

Column chromatography separates compounds based on their polarity. The more polar a compound is, the more it interacts with the stationary phase and the slower it moves through the column. The less polar a compound is, the faster it moves through the column. As the chromatogram, degree of polarity → a > b > c ∴ Statements A ,   B are incorrect as b comes out before ‘ C ’ the statement C is also incorrect. As a is most polar, it spends most time. Hence, A ,   B and C are inc
