WebJul 7, 2024 · When phenol is treated with neutral FeCl3 it gives violet colour? The theory behind this is that phenolic compounds react with neutral ferric chloride solutions to give coloured compounds like blue, violet, green . This is due to the formation of phenoxide ions which give coloured complex compounds that are soluble in water. So option C is correct. WebPhenols are reacted with ferric chloride. Different colours are observed which makes the process useful for phenol determinations. At least as qualitative determination. Show more. Show more ...
