Question

The tests performed on compound $X$ and their inferences are given below:

Test	Inference
(a) 2,4-DNP test	Coloured precipitate
(b) Idoform test	Yellow precipitate
(c) Azo-dye test	No dye formation

Compound '$X$' is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is B


Compound (c) is an alcohol which does not gives positive 2,4-DNP test. Hence, eliminated. Compounds (a) and (d) do not have $-COC{H}_3$ group and therefore do not give idoform test. Hence, eliminated.
