The diаgrаm belоw shоws а thin-layer chrоmatogram of a mixture of products from a chemical reaction. The separation was performed using 50% ethyl acetate in hexane as the solvent (mobile phase) and silica gel as the polar stationary phase. On the basis of the chromatogram and the information about solvents in the table, which of the following would be the best way to decrease the distance that the products travel up the plate? The figure presents a diagram of a thin-layer chromatogram. The diagram is in the shape of a rectangle and divided into 3 sections. The top section is divided with a dashed line that is labeled Solvent Front. The middle section, which is the biggest section, has a smaller dark oval above a bigger dark oval. The ovals are close but are not touching. The ovals are in the upper half of the middle section and are labeled Product. The bottom section is divided with a solid line that is labeled Origin.
