Solution: Ferric chloride can be used to distinguish between phenol and benzyl alcohol.
How can you distinguish between phenol and benzyl alcohol?
(i) Phenol turns blue litmus red but benzyl alcohol does not. (ii) Phenol gives a white precipitate with bromine water but benzyl alcohol does not.
Which reagent can be used to distinguish between phenol and benzyl alcohol?
Phenols react with neutral ferric chloride solution to give blue, violet or green colouration whereas alcohols do not react.
Which of the following Cannot be used to distinguish phenol and benzyl alcohol?
Firstly, we have aqueous NaOH. Benzoic acid will react with it and will result in formation of sodium benzoate through the formation of a benzoate ion. Similarly, phenol reacts with sodium hydroxide and gives a phenoxide ion. Both solutions are colourless so we cannot use it to determine the two.
Which of the following test is used to distinguish benzyl alcohol?
Aniline gives dye test on diazotisation and reaction with β−naphthol, while benzylamine gives alcohol.
Which test is used to distinguish between benzyl alcohol and acetaldehyde?
Fehling’s solution can be used to distinguish benzaldehyde from acetaldehyde.
Can litmus solution be used to distinguish phenol and benzyl alcohol?
Litmus Test. … Phenol being acidic turns blue litmus red while benzyl alcohol being neutral does not give this test. Phenol decolourises bromine water giving a white ppt. of 2, 4, 6-tribromophenol while benzyl alcohol does not give this test.
Which of the following can be used to distinguish ethanol and phenol?
(i) Ethanol and phenol Iodoform test is used to distinguish ethanol and phenol. Ethanol reacts with NaOH solution containing iodine. On heating, it gives a yellow precipitate of iodoform while phenol does not react.
How do you distinguish between alcohol and phenol?
Test to distinguish between alcohol and phenols
- Litmus test : Phenols turn blue litmus red and alcohols have no effect.
- Ferric chloride test : Phenols give blue, green, and violet color while alcohol give no change in color.
- Bromine water test : Phenols gives white precipitates while alcohol give no precipitates.
Which reagents Cannot be used to differentiate phenol and ethanol?
Phenol is acidic in nature while ethanol is a very weak acid. It is almost neutral. So red litmus paper will remain unchanged in both phenol and ethanol so it cannot be used to distinguish Phenol and ethanol.
Which of the following reagents may be used to distinguish between phenol and?
Which of the following reagents may be used to distinguish between phenol and benzoic acid ? Tollen ‘s reagent. Phenol gives violet colour with neutral FeCl3 while benzoic acid gives buff coloured ppt.
