    Advantages
    1. The density of ether is less than 1. It forms separate layers with aqueous solutions, it has limited solubility in water (Ether is sparingly soluble in water (6.9 g/100 mL).

    2. Ethers are aprotic polar solvents which dissolves most of the organic compounds

    3. The melting point of ethers are negative ...

    Solution Summary

    This solution provides a detailed description of the advantages and disadvantages of ether in solvent extraction. The solvent extraction is the process of the separation of organic compounds using a solvent system. Additionally, this solution explains why the stopper at the top of the separatory funnel must be removed before liquid can be withdrawn through the stopcock.
