The appearance of the spots on the TLC plate in case of the solvent of low and high polarities should be determined. Concept introduction: TLC works on the principle of separation of constituents of a mixture of compounds based on polarity. The polar compounds interact with the stationary phase thus can move to smaller distance from the base. While the non-polar compounds tend to move faster as they interact less with the silica gel, therefore, they move far from the base of the plate.

Question

Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х а
