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

A

`Br_(2) + H_(2)O`

B

`FeCl_(3)`

C

`I_(2)+NaOH`

D

Both (a) and (c)

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(2)H_(5)OH and C_(6)H_(5)OH` can be distinguished by neutral `FeCl_(3)` solution or `I_(2)+NaOH` solution
`C_(2)H_(5)OH` gives iodoform test with `I_(2)+NaOH` solution while phenol does not give yellow ppt. of iodoform.
`C_(2)H_(5)OH + 4I_(2)+ 6NaOH overset(Delta)to underset("iodoform")(CHI_(3))+ NCOONa+5NaI + 5H_(2)O`
`C_(6)H_(5)OH + I_(2) + NaOH to ` No reaction
`C_(6)H_(5)OH` reacts with neutral `FeCl_(3)` solution to give purple colour while `C_(2)H_(5)OH` does not give any colour with neutral `FeCl_(3)` solution.
