Question

Very confused with this. Please help.

A student runs a TLC plate of a mixture of four compounds. The TLC plate is shown below. How could the student improve the TLC plate (i.e. how could the student improve the separation of the compounds)? a b с d e Spot more sample onto the plate. 5:1 petroleum ether: diethyl ether Use only petroleum ether as the eluant. Change the eluant to a 10:1 mixture of petroleum ether to diethyl ether Change the eluant to a 3:1 mixture of petroleum ether to diethyl ether Spot less sample onto the plate.
