Question

1: Complete the data table by placing a check mark or an X in each box to indicate whether the molecule in each row of the left-most column would give a positive test with the reagents listed in each column.

2: Natural products can be extracted into organic solvent. For example, limonene can be extracted from the largely-aqueous distillate of a steam distillation of orange peel by ethyl acetate, and eugenol can be extracted from aqueous solution into dichloromethane. The diagrams below represent the separatory funnels for the two different solvent systems. Drag and drop the layers into the appropriate box.

Bromine Potassium permanganate Ferric chloride Click on an item, then drag it to the appropriate box cyclohexene limonene eugenol

Explanation / Answer

1.

                                   Bromine           KMnO4           FeCl3

cyclohexene                  +ve                  +ve                -ve

limonene                       +ve                  +ve                -ve

eugenol                         +ve                  +ve                +ve

2.

In the separation technique, density of solvent is considered.

                            water/ethylacetate            water/dichlormethane

Top layer                  ethylacetate                           water

Bottom layer                 water                          dichlormethane
