Write chemical test to distinguish between the following compounds:
Phenol and Benzoic acid
Give chemical test to distinguish between the following pair of compound:
Phenol and Benzoic acid
Solution 1
Phenol and Benzoic Acid can be distinguished by the iron chloride FeCl3 test. As phenol gives violet colouration with neutral FeCl3, solution while benzoic acid gives buff-coloured precipitate of ferric benzoate.
Solution 2
| Reagent | Phenol | Benzoic acid |
| Neutral ferric chloride | When phenol is treated with ferric chloride, there is a change in colour; the product formed is either green, blue, purple, or red. | No change in the colour of benzoic acid. |
