Q. The tests performed on compound X and their inferences are

Test Inference

$\left(1\right)$ 2,4- DNP test coloured precipitate

$\left(2\right)$ iodoform test yellow precipitate

$\left(3\right)$ Azo dye test no dye formation

Compound 'X' is

NTA AbhyasNTA Abhyas 2020Aldehydes Ketones and Carboxylic Acids

Solution:

Information (1) indicates that compound has a carbonyl $\begin{bmatrix} \, & O & \, \\ \, & \left|\right.\left|\right. & \, \\ - & C & - \end{bmatrix}$ group.

Information (2) indicates that compound has a methyl ketone $\left(\right.CH_{3}—\overset{O}{\overset{\left|\right. \left|\right.}{C}}—\left.\right)$ group.

Information (3) indicates that it is 3° amine and not 1° amine so answer is $\left(\right.B\left.\right)$ which gives 2, 4-DNP test and iodoform test.
