# If dichloromethane (DCM) and water

Question:

If dichloromethane (DCM) and water $\left(\mathrm{H}_{2} \mathrm{O}\right)$ are used for differential extraction, which one of the following statements is correct?

1. $\mathrm{DCM}$ and $\mathrm{H}_{2} \mathrm{O}$ would stay as lower and upper layer respectively in the S.F.

2. DCM and $\mathrm{H}_{2} \mathrm{O}$ will be miscible clearly

3. $\mathrm{DCM}$ and $\mathrm{H}_{2} \mathrm{O}$ would stay as upper and lower layer respectively in the separating funnel (S.F.)

4. $\mathrm{DCM}$ and $\mathrm{H}_{2} \mathrm{O}$ will make trubid/colloidal mixture

Correct Option: 1

Solution:

(1) DCM and $\mathrm{H}_{2} \mathrm{O}$ would stay as lower and upper layer respectively in the S.F.
