The product is an imine formed by a reaction between 2 mmol

The product is an imine formed by a reaction between 2 mmol of p-chlorobenzaldehyde and 2 mmol of p-anisidine, allowed to react to completion.

Which of the following best describes a reasonable procedure for the liquid/iquid extraction: A combination of two aqueous solutions (such as aqueous sodium hydroxide and aqueous hydrochloric acid) should be used for the extraction, and the product will partition into the more based of the two solutions A combination of water and an organic solvent (hexanes or ethyl acetate) should be used for the extraction, and the product is likely to partition into the organic solvent layer. A combination of two organic solvents (such as hexanes or ethyl acetate) should be used for the extraction, and the product will partition into the more polar of the two solvents A combination of water and an organic solvent (hexanes or ethyl acetate) should be used for the extraction, and the product is likely to partition into the water layer.

Solution

Answer:

Liquid-Liquid Extraction utilizes binary phases involving a combination of Aqueous phase (Polar phase) -NonAqueous phase (relatively less polar or non-polar phase).

The aqueous phase is generally Water & organic/NonAqueous phase is generally Hydrocarbon or Ethers.

When an Organic compound is expected to be separated from the reaction mixture, Liquid-Liquid Solvent extraction technique is employed. And hence obviously an Organic compound following Like dissolves Like principle do get extracted in Organic phase.

Hence of the given choices, A combination of water & organic solvent (Hexanes/Ethyl acetate) should be used for extraction & product is likely to partition into organic solvent Layer - Best explains the L-L Extraction of Imine.
