Current Question (ID: 10974)

Question:

$\text{Match Column I with Column II.}$ $\text{Column I}$ $\text{A. Dumas method}$ $\text{B. Kjeldahl's method}$ $\text{C. Carius method}$ $\text{D. Chromatography}$ $\text{Column II}$ $\text{1. AgNO}_3$ $\text{2. Silica gel}$ $\text{3. Nitrogen gel}$ $\text{4. Ammonium sulphate}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $\text{A-3, B-4, C-1, D-2}$ (Correct)
2. $\text{A-1, B-2, C-3, D-4}$
3. $\text{A-1, B-4, C-3, D-2}$
4. $\text{A-4, B-1, C-3, D-2}$

Solution:

$\text{Hint: Quantitative analysis}$ $\text{Column I}$ $\text{A. Dumas method - Nitrogen gel - Used for N containing compounds}$ $\text{B. Kjeldahl's method - Ammonium sulphate - Nitrogen converts to ammonium sulphate}$ $\text{C. Carius method - AgNO}_3\text{ - The compound is heated in presence of AgNO}_3$ $\text{D. Chromatography - Silica gel - The adsorbent used is silica gel}$ $\text{Therefore, the correct matching is:}$ $\text{A-3 (Nitrogen gel), B-4 (Ammonium sulphate), C-1 (AgNO}_3\text{), D-2 (Silica gel)}$
