Good evening sir ! It's urgent, Sir I wanna know why RF value of molecules are different? Answer me in an hour please sir Today is last day to submit of assignment
@pkclasses1004 жыл бұрын
Rf values of molecules are different because each molecule is having different affinity with that stationary phase and mobile phase. So, migration rate is different for different molecules in the chromatography.
