- wherein

Mixture of acetone and methyl alcohol

 

as we have learned in sepration methods

If DCM and H2O are used for differential extraction, DCM will stay as lower and H2Owill stay as upper layer in the seperating funnel.

 


Option 1)

DCM \: \: and\: \: H_{2}O would stay as lower and upper layer respectively in the S.F.

Option 2)

DCM \: \: and\: \: H_{2}O will make turbid / colloidal mixture .

Option 3)

DCM \: \: and\: \: H_{2}O would stay as upper and lower layer respectively in the separating funnel (S.F.)

Option 4)
