MCQ
The tests performed on compound $X$ and their inferences are

Test Interference
$(a)$ $2, 4-DNP$ test Colorued precipitate
$(b)$ Iodoform test Yellow precipitate
$(c)$ Azo-dye test No dye formation

Compound $‘X’$ is

  • A


  • C

  • D

Answer

Correct option: B.

b
$\because  \,\,-COCH_3$ is present it will show both $2, 4-DNP$ and iodoform test. Due to steric inhibition of resonance. $I.P$ of $‘N’$ is not involved in delocalization so coupling reaction will not take place.
