Question

In the Victor Meyer test, a specific sequence of color changes is used to distinguish the degree of an alcohol. What is the final color observation for a secondary alcohol after sequential treatment with $P/I_2$, $AgNO_2$, $HNO_2$, and aqueous $NaOH$?

Prashant Kotian · Accepted Answer

Correct answer: B. In the Victor Meyer test, primary alcohols yield a blood-red color (due to nitrolic acid salts), secondary alcohols yield a blue color (due to pseudonitrole), and tertiary alcohols remain colourless as they do not react with nitrous acid.
