Answer:
Victor Meyer's Test is a test to distinguish whether a given alcohol is primary, secondary or tertiary.... This upon reaction with AgNO2 gives nitroalkane, which on reaction with HNO2 gives different compounds for different alcohols like nitrolic acid for primary alcohol, pseudonitriol for secondary alcohol etc.
Answer:
- Victor Meyer Method of Alcohol Distinction
The nitroalkane is then treated with nitrous acid which is obtained by NaNO2 and HCl. The resulting solution is treated with KOH and the colour is observed. The red, blue and no colour indicates the primary, secondary and tertiary alcohol respectively.
The nitrosation of primary aromatic amines with nitrous acid (generated in situ from sodium nitrite and a strong acid, such as hydrochloric acid, sulfuric acid, or HBF4) leads to diazonium salts, which can be isolated if the counterion is non-nucleophilic.
2. Diazonium salts are important intermediates for the preparation of halides (Sandmeyer Reaction, Schiemann Reaction), and azo compounds. Diazonium salts can react as pseudohalide-type electrophiles, and can therefore be used in specific protocols for the Heck Reaction or Suzuki Coupling.
The intermediates resulting from the diazotization of primary, aliphatic amines are unstable; they are rapidly converted into carbocations after loss of nitrogen, and yield products derived from substitution, elimination or rearrangement processes
