Chapter 8, Problem 9Q

Interpretation Introduction

Interpretation:

The appearance of the spots on the TLC plate in case of the solvent of low and high polarities should be determined.

Concept introduction:

TLC works on the principle of separation of constituents of a mixture of compounds based on polarity. The polar compounds interact with the stationary phase thus can move to smaller distance from the base. While the non-polar compounds tend to move faster as they interact less with the silica gel, therefore, they move far from the base of the plate.
