Question

Match the column I with column II and mark the appropriate choice.

	Column I		Column II
1	Beilstein test	1	Sulphur
2	Sodium nitroprusside	2	Carbon
3	Liebig's method	3	Nitrogen
4	Kjeldahl's method	4	Chlorine

• A. $\left(A\right)=\left(i\right),\left(B\right)=\left(ii\right),\left(C\right)=\left(iii\right),\left(D\right)=\left(iv\right)$
• B. $\left(A\right)=\left(iii\right),\left(B\right)=\left(ii\right),\left(C\right)=\left(i\right),\left(D\right)=\left(iv\right)$
• C. $\left(A\right)=\left(iv\right),\left(B\right)=\left(i\right),\left(C\right)=\left(ii\right),\left(D\right)=\left(iii\right)$
• D. $\left(A\right)=\left(ii\right),\left(B\right)=\left(iii\right),\left(C\right)=\left(iv\right),\left(D\right)=\left(i\right)$

Answer 1

The correct option is C $\left(A\right)=\left(iv\right),\left(B\right)=\left(i\right),\left(C\right)=\left(ii\right),\left(D\right)=\left(iii\right)$

(A) Beilstein test $\to$ This test is employed to detect the presence of halogen in an organic compound. $\to \left(iv\right)$ Chlorine

(B) Sodium nitroprusside $\to {Na}_2\left[Fe{\left(CN\right)}_{5}NO\right]$ is used in Lassaigne's test to detect the presence of Sulphur. $\to \left(i\right)$ Sulphur

(C) Liebig's method $\to$ It is used for the estimation of carbon and hydrogen. The carbon dioxide and water formed are collected and weighed. $\to \left(ii\right)$ Carbon

(D) Kjeldahl's method $\to$ It is used for the quantitative determination of nitrogen contained in organic substances plus the nitrogen contained in the inorganic compounds ammonia and ammonium $\left(N{H}_3/{N{H}_4}^{+}\right).\left(iii\right)\to$ Nitrogen
