Q7 / 54 · JEE Advanced 2016 (Paper 1) · Chemistry

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

A
R is steam volatile
Correct answer
B
Q gives dark violet coloration with $1 %$ aqueous $F e C l_{3}$ solution
Correct answer
C
S gives yellow precipitate with 2,4-dinitrophenylhydrazine
D
S gives dark violet coloration with $1 %$ aqueous $F e C l_{3}$ solution

Solution

Q gives dark violet coloration with $1 %$ aqueous $F e C l_{3}$ solution because it has phenolic (-OH) group.

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

F e C l_{3}

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

Hence, the correct answer is options: 'B', 'C'.
