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

1. DCM and H 2 O would stay as upper and lower layer respectively in the separating funnel (S.F.)
2. DCM and H 2 O will make turbid/ colloidal mixture
3. DCM and H 2 O would stay as lower and upper layer respectively in the S.F.
4. DCM and H 2 O will be miscible clearly

Correct answer: DCM and H 2 O would stay as lower and upper layer respectively in the S.F.
