Identify the binary mixtures (s) that can be separated into the individual compounds, by differential extraction, as shown. In the given scheme-

Answer»

`C_(6)H_(5)OH` and `C_(6)H_(5)COOH`
`C_(6)H_(5)COOH` and `C_(6)H_(5)CH_(2)OH`
`C_(6)H_(5)CH_(2)OH` and `C_(6)H_(5)OH`
`C_(6)H_(5)CH_(2)OH` and `C_(6)H_(5)CH_(2)COOH`

Solution :Acidic strength order of some organic COMPOUNDS
`C_(6)H_(5)COOH,C_(6)H_(5)CH_(2)CO_(2)HgtH_(2)CO_(3)gtC_(6)H_(5)OHgtH_(2)OgtC_(6)H_(5)CH_(2)OH`
(A) `C_(6)H_(5)OH,C_(6)H_(5)COOHrarr`separated by `NaHCO_(3)` only but not by NaOH`
(B) `C_(6)H_(5)COOH,C_(6)H_(5)CH_(2)OHrarr` sparated by `NaHCO_(3) & NaOI I` both.
(C) `C_(6)H_(5)CH_(2)OH,C_(6)H_(5)OHrarr` separated by `NaOH` only but npt nu `NaHCO_(3)`
(D) `C_(6)H_(5)CH_(2)OH,C_(6)H_(5)CH_(2)COOHrarr` separated by `NaHCO_(3) & NaOH` both.
