Step-by-step solution

Step-by-Step SolutionStep 1: Extraction

A technique that is employed to segregate and purify various substances is extraction. Various solvents used for extraction include an organic solvent like dichloromethane and aqueous solvent like water.

Separation of compounds by extraction

A separatory funnel is utilized for the segregation of various substances in extraction.

The incorporation of two insoluble liquids into the separatory funnel leads to the formation of two layers. The less-dense layer is found on top, and a more dense layer is found on the bottom.

Compounds that can be separated by the extraction procedure

The compounds should have different solubility properties in order to separate them by extraction procedure.

a. The given pair of compounds can be separated by extraction procedure as the acid can be extracted to the aqueous base, and the alkene will stay in the organic layer.

b. These compounds cannot be separated as both compounds dissolve in organic solvents and are insoluble in water. Both the compounds are not acidic to be extracted to the aqueous base.

c. The given compounds can be separated, as one compound is a carboxylic acid and the other compound is a salt. The carboxylic acid can be dissolved in organic solvent and the salt can be dissolved in water.

d. The given compounds cannot be separated as both of them are salts. They dissolve in the water layer.
