Question

Answer is option 3.

Compound 3 will have thelargest Rf value.

Rf value is used to quantify the movement of the materials along the plate. Rf is equal to the distance traveled by the substance divided by the distance traveled by the solvent. It's value is always between zero and one.

Silica gel consists of a three-dimensional network of thousands of alternating silicon and oxygen bonds, with O-H groups on the outside surface. Silica gel is simply very finely ground very pure sand. It should be noted that silica gel is highly polar and is capable of hydrogen bonding.

The polarity of molecules, solutes and solvents alike, is ordered as follows, from least to most polar:
Alkanes (least polar), alkyl halides, alkenes, aromatic hydrocarbons, ethers, esters, ketones, aldehydes, amines, alcohols, and carboxylic acids (most polar).

So, compound 3 (an aromatic hydrocarbon) is the least polar and will have largest Rf value.
