In regards to the seperation of fluorene and 9-fluorenone by column chromatograp

Question

In regards to the seperation of fluorene and 9-fluorenone by column chromatography, calculate the % yield with and without taking into account the amount of recovered fluorene. Amount of fluorene recovered: 0.5g Amount of 9-fluorenone recovered: 0.05g In regards to the seperation of fluorene and 9-fluorenone by column chromatography, calculate the % yield with and without taking into account the amount of recovered fluorene. Amount of fluorene recovered: 0.5g Amount of 9-fluorenone recovered: 0.05g Amount of fluorene recovered: 0.5g Amount of 9-fluorenone recovered: 0.05g

Explanation / Answer

% Yield = (Actual yield / total quantity) x 100 if % Yield of 9-fluorenone = (0 .05/ .55 ) x 100 = 9.09 %

total quantity = 0.5 + 0.05 = 0.55 gms

  % Yield of fluorene = (0 .5/ 0.55 ) x 100 = 90.90 %
