Question

Match List I (Substances) with List-II (Processes employed in the manufacture of the substance) and select the correct option.

List - I (Substances)	List - II (Processes)
A. Sulphuric acid	$1.$ Haber's process
B. Steel	$2.$ Bessemer's process
C. Sodium hydroxide	$3.$ Leblanc process
D. Ammonia	$4.$ Contact process

• A. $A-1,B-4,C-2,D-3$
• B. $A-1,B-2,C-3,D-4$
• C. $A-4,B-3,C-2,D-1$
• D. $A-4,B-2,C-3,D-1$

Answer 1

Answer: (D)

$A-4,B-2,C-3,D-1$

The contact process is used for $\text{sulphuric acid}$ and $\text{steel}$ is manufactured by Bessemer's process.

Leblanc process is used for the production of $NaOH$ while Haber's process is used for $N{H}_3$ production.

Hence, option $D$ is correct.
