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

Options

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

Correct answer

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

Step-by-step solution

Dichloromethane and water are immiscible in nature. Also, Dichloromethane has higher density than water so forms bottom layer (Layer II) in the separating funnel.
