Question

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.

Quantrex Academy · Accepted Answer

Correct answer: D. A, C and E only

(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
