Vedclass · Answer

(A) The Liebermann nitroso reaction is a test for phenols. When phenol is treated with sodium nitrite $(NaNO_2)$ and concentrated sulfuric acid $(H_2SO_4)$,it forms a nitroso compound. The reaction proceeds with a characteristic color change: $1$. The solution initially turns red or brown. $2$. Upon dilution with water,it turns green. $3$. Finally,upon adding an alkali (like $NaOH$),it turns deep blue. Therefore,the sequence is Brown or red $	o$ Green $	o$ Deep blue.

In the Liebermann nitroso reaction,what is the sequence of color changes observed in phenol?
