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.
How can you distinguish between benzene and phenol?
What is the Difference Between Benzene and Phenol? The key difference between benzene and phenol is that phenol has a –OH group in place of a hydrogen atom in benzene. Benzene is an organic compound having the chemical formula C6H6 while Phenol is a white crystalline solid with molecular formula C6H6OH.
How can you tell the difference between ethyl alcohol and benzyl alcohol?
Answer: CH3CH2OH is the chemical formula of ethyl alcohol. whereas chemical formula of benzyl alcohol is C6H5CH2OH.
Which of the following 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.
How will you distinguish between phenol and methyl alcohol?
Phenol, aromatic alcohol, reacts easily with an aqueous solution of FeCl3 to give a violet color. On the other hand, no aliphatic alcohol (For example, ethyl alcohol, methyl alcohol, etc.) will react with a solution of FeCl3. When handled with aqueous Br2 phenol, the white precipitate is 2,4,6-tribromophenol.
How can you distinguish the following pairs of compounds phenol and methyl alcohol?
Phenol gives a violet colouration with FeCl3 solution while methanol does not.
Which test is used to distinguish between benzyl alcohol and acetaldehyde?
Fehling’s solution can be used to distinguish benzaldehyde from acetaldehyde.
Which of the following test is used to distinguish benzyl alcohol?
You can perform Tollens test or Benedicts test. Since benzaldehyde is a carbonyl compound, it will give silver mirror in Tollens test and will give red ppt in Benedicts test. Since benzyl alcohol is an alcohol, it cannot give these tests.
