Which of the following amino acid will give violet coloured complex with neutral ferric chloride solution?
- A Threonine
- B Serine
- C Tyrosine
- D Cysteine
Answer & Solution
Correct Answer
(C) Tyrosine
Step-by-step Solution
Detailed explanation
Neutral ferric chloride (\(\text{FeCl}_3\)) solution gives a characteristic violet coloured complex with compounds containing a phenolic hydroxyl group. Among the given amino acids, Tyrosine contains a phenolic \(-\text{OH}\) group in its side chain. Threonine and Serine contain…
