Crackerol and tinselene have Rf values of 0.47 and 0.24 respectively. If the TLC was run on a TLC plate where the solvent front moved 9.9 cm from the baseline, what would be the distance in centimetres (cm) between the spots for the two compounds?

Answer #1

Rf = distance moved by the compound or spot / distance moved by the solvent.

Here for

Crackerol has Rf values of 0.47

and tinselene has Rf values of 0.24

and distance moved by the solvent = 9.9 cm

Crackerol

Rf = distance moved by the compound or spot / distance moved by the solvent.

0.47= distance moved by the Crackerol / 9.9 cm

distance moved by the Crackerol = 4.7 cm

tinselene

Rf = distance moved by the compound or spot / distance moved by the solvent.

0.24= distance moved by the tinselene / 9.9 cm

distance moved by the tinselene = 2.4 cm

the distance in centimetres (cm) between the spots for the two compounds is

4.7 cm-2.4 cm = 2.3 cm

The TLC chromatogram shows the result for a separation of a mixture of three compounds using a solvent of medium polarity. Only two spots are visible because two compounds did not separate. If spot A represents a mixture of two compounds, would you be able to separate the two components by decreasing or increasing the solvent polarity? Please explain. Sketch the TLC’s that you would expect to see if you were to develop a TLC in a) a polar solvent,...

A student developed a TLC plate by spotting the sample 1 cm from the bottom and allowed the solvent to move up to a point 1 cm from the top. He developed this TLC in 30% ethyl acetate in hexane and got a single spot with Rf value 0.3. If the distance travelled by the solvent front was 8 cm, calculate the distance travelled by the spot. Also, calculate the length of the TLC plate he used to do this...

You run a reaction with column chromatography and you find that you have multiple products (cyclohexene from cyclohexanol). You predictyou have the alcohol functionality you were trying to make and the alkene from the eliminated product (some of the alochol must have elimited to form the alkene). You run a few TLCs to find a good solvent to run a column in order to separate two products. You decide on a 10% ethyl acetate in hexanes because it allows one...
