Consider an analysis of the TLC plate obtained eluting a dilute solution of compound X on a silica gel plate using 1:1 by volume hexanes:ethyl acetate. The TLC plate was coated with a fluorescent indicator and had dimensions of 7.0 cm by 2.0 cm. The compound was spotted onto the TLC at the origin, 1.0 cm above the bottom of the plate. The solvent front was marked 1.5 cm from the top of the plate. Using a UV Vis hand help lamp (254 nm) the center point of the dark spot that was believed to be compound X was determined to have been 3.2 cm from the origin. What is the Rf of compound X ( reported as #.## )
