Phenols react with neutral ferric chloride, then which coloration is NOT produced?
- APurple
- Bviolet
- Cgreen
- Correct answerDBlack
Solution
Phenols react with neutral ferric chloride to form water-soluble coordination complexes. The color of the complex depends on the structure of the specific phenol.
Common colors observed during this test are violet, blue, green, purple, and red. For example, phenol gives a violet color, cresols give a blue color, and catechol gives a green color.
Black coloration is not produced by phenols upon reaction with neutral ferric chloride.
