If dichloromethane (DCM) and water `(H_(2)O)` are used for differential extraction, which one of the following statements is correct ?

Options

A. DCM and `H_2O` will make turbid/colloidal mixture
B. DCM and `H_2O` will be miscible clearly
C. DCM and `H_2O` would stay as lower and upper layer respectively in the separating funnel
D. DCM and `H_2O` would stay as upper and lower layer respectively in the separating funnel (S.F.)

Answer

C

Explanation

(a) All Alkyl Halides are absolutely water insoluble.
(b) All Alkyl Halides are dense as compared to water.
(c) In a separating funnel upper layer is called layer-1 and the lower layer is called layer-2.
(d) So, the upper layer will be with less dense `H_2O` and the lower layer will be denser DCM.
