MCQ
On a thin layer chromatographic plate, an organic compound moved by $3.5 \mathrm{~cm}$, while the solvent moved by $5 \mathrm{~cm}$. The retardation factor of the organic compound is____ $\times 10^{-1}$
- A$06$
- ✓$07$
- C$8$
- D$5$
✓
Answer
Correct option: B.
$07$
b
Retardation factor $=\frac{\text { Distance travelled by sample/organic compound }}{\text { Distance travelled by solvent }}$ $=\frac{3.5}{5}=7 \times 10^{-1}$
Retardation factor $=\frac{\text { Distance travelled by sample/organic compound }}{\text { Distance travelled by solvent }}$ $=\frac{3.5}{5}=7 \times 10^{-1}$
