An atom that has lost an election becomes a positively charged ion and it's called a<em> </em><em>cation</em>
Answer:
The Rf value of the compound is 0.33
Explanation:
Rf value is known as the retention factor value. It is commonly used in paper chromatography and thin layer chromatography for comparing and analyzing different substances. The retention factor (Rf) value is the ratio of the distance moved by a substance from the origin to the distance moved by the solvent front from the origin. The Rf value ranges from 0 to 1.
Rf = Distance the substance moved / Distance the solvent front moved
From the question,
Distance the substance (compound) moved = 20 millimeters
Distance the solvent front moved = 60 millimeters
Hence,
Rf = 20 millimeters / 60 millimeters
Rf = 0.33
Hence, the Rf value of the compound is 0.33.
