JEE Mains · Chemistry · STD 12 - 8.2 Carboxylic acids and their derivative
Given below are the four isomeric compounds (P, Q, R, S)
Identify correct statements from below.
A. Q, R and S will give precipitate with 2, 4 - DNP.
B. P and Q will give positive Bayer's test.
C. Q and R will give sooty flame.
D. R and S will give yellow precipitate with. \(I _2 / NaOH\).
E. Q alone will deposit silver with Tollen's reagent
Choose the correct option.
- A A, C and E only
- B A and E only
- C C and E only
- D A, B, D and E only
Answer & Solution
Correct Answer
(A) A, C and E only
Step-by-step Solution
Detailed explanation
(A) Q, R, S all three give 2, 4 DNP test as they have Aldehyde/ketone group (C) Q & R gives sooty flame (E) Q gives Tollens reagent test
