5
Q
Prepare the COLUMN
A
Top: Thin Layer of Sand Alumina Sample Solvent Sand Bottom:Cotton
6
Q
Fraction 1:
A
Yellow(mobile phase) ferrocene
7
Q
Fraction 3
A
Orange(stationary phase) acetylferrocene
8
Q
Acetylferrocene is
A
More polar meaning it’ll be more stationary(high affinity to polar)
9
Q
Ferrocene
A
High affinity to LOWER polarity (mobile phase)
