`C_(2)H_(5)OH and C_(6)H_(5)OH` can be distinguished by

Options

A. `Br_(2)+H_(2)O`
B. `FeCl_(3)`
C. `l_(2)+NaOH`
D. Both (b) and (c)

Answer

D

Explanation

`C_(2)H_(5)OH and C_(6)H_(5)OH` can be distinguished by neutral `FeCl_(3)` solution or `l_(2)+NaOH` solution. `C_(2)H_(5)OH` gives iodoform test wit `l_(2)+NaOH` solution while phenol does not give yellow ppt. of iodoform.
`C_(2)H_(5)OH+4I_(2)+6NaOH overset(Delta)rarr underset("Iodoform")(CHI_(3))+HCO overset(-)O overset(+)Na+5NaI+5H_(2)O`
`C_(6)H_(5)OH+l_(2)+NaOH rarr "No reaction"`
`C_(6)H_(5)OH` reacts with neutral `FeCl_(3)` solution to give purple colour while `C_(2)H_(5)OH` doesn't give any colour with neutral `FeCl_(3)` solution.
