Explanation:
Part a
Normal Phase Chromatography
In the normal phase chromatography, the eluting power is highest for the solvent which has the highest polarity.
So from the given solvents as Methanol, Dichloromethane and Ethyl Acetate
the relative polarities are given as
Methanol=0.762
Dichloromethane (methylene chloride)=0.309
Ethyl Acetate=0.228
So the numbers are given as
Methanol :1
Dichloromethane (methylene chloride):2
Ethyl Acetate:3
Reverse Phase Chromatography
In the reverse phase chromatography, the eluting power is highest for the solvent which has the lowest polarity.
So from the given solvents as diethyl ether , water and toluene
the relative polarities are given as
Diethyl ether=0.117
Water=1.0
Toluene=0.099
So the alphabets are given as
Toluene :A
Diethyl ether: B
Water:C
