Correct answer: B
-
We match each test/method with its correct reagent.
-
Lucas Test
- Lucas test is used to distinguish alcohols.
- Reagent used: conc. HCl and anhydrous ZnCl.
- So,
-
Dumas method
- Dumas method is used for estimation of nitrogen.
- The organic compound is heated with CuO, and nitrogen is measured after conversion of C and H into oxides.
- Among the given options, this corresponds to:
-
Kjeldahl’s method
- Kjeldahl’s method involves digestion with concentrated HSO.
- Hence,
-
Hinsberg test
- Hinsberg test for amines uses benzenesulphonyl chloride in aqueous KOH.
- Therefore,
-
Final matching:
-
Compare with options:
- This corresponds to Option B.
