1. If the Rf of a compound is 0.860 and the compound moved 5.34 cm, calculate the distance the solvent front moved.

Answer 1

Answer #1

Given

Distance moved by compound = 5.34 cm

R _f value of a compound = 0.860

Distance the solvent front moved = ?

We know that, Retardation factor ( R _f ) = Distance moved by compound / Distance the solvent front moved

Distance the solvent front moved = Distance moved by compound / R _f

Distance the solvent front moved = 5.34 cm / 0.860

Distance the solvent front moved = 6.209 cm

ANSWER : Distance the solvent front moved = 6.21 cm
