The advantages and limitations of FFF in comparison to chromatographic methods needs to be explained. Concept introduction: Chromatographic methods involve a group of separation techniques that are effective in separating liquids and gases. There are two phases involved in this method, namely stationary phase and mobile phase. FFF or Field flow fractionation is a type of analytical method of separating particles wherein the solution is pumped through the channel perpendicular to the direction of flow. Here the sample separation is carried out in single liquid phase. The force applied defines the separation process.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. • If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T G OH де OH This transformation can't be done in one step.
