The correct statement(s) about of the following reaction sequence is(are)

Options

AR is steam volatile
BQ gives dark violet coloration with $1%$ aqueous $FeC{l}_{3}$ solution
CS gives yellow precipitate with 2,4-dinitrophenylhydrazine
DS gives dark violet coloration with $1%$ aqueous $FeC{l}_{3}$ solution

Correct answer

B. Q gives dark violet coloration with $1%$ aqueous $FeC{l}_{3}$ solution

Step-by-step solution

The correct statement(s) about of the following reaction sequence is(are)

The correct statement(s) about of the following reaction sequence is(are)
Q gives dark violet coloration with $1\text{%}$ aqueous $\text{F}\text{e}\text{C}{\text{l}}_{3}$ solution because it has phenolic (-OH) group.

* Q is steam Volatile not R.
Q & R show positive test with 1%

\text{F}\text{e}\text{C}{\text{l}}_{3}

solution
Q, R, S Show positive 2, 4 dinitrophenylhydrazine.
