The compound that does not give a blue color in Lassaigne's test is

A

B

hydrazine

C

urea

D

aniline

Text Solution

Verified by Experts

The correct Answer is:
B
Hydrazine `(H_(2)N NH_(2))` has nitrogen but does not give Prussian blue color in Lassaigne's test because it does not contain `C` and, thus, cannot form `NaCN` required for the formation of ferri ferrocyanide.
