Phenol Flashcards
What is phenolic - OH group?
-OH group which is directly bonded to Benzene ring.
Why does phenol not displace CO2 from NaHCO3 solution?
Since phenol is less acidic than carbonic acid.
What are the two tests for phenols?
- Neutral Ferric Chloride test
- Phthalein dye test
Explain Neutral Ferric Chloride test for phenol.
When phenol is treated with Neutral ferric chloride, a violet colour is obtained.
Explain phthalein dye test for phenol.
When phenol is poured into a dilute sodium hydroxide, a pink coloured solution is formed.
What causes the pink colour in phthalein dye test?
It is due to formation of phenolphthalein.
