Q. Match List-I (substances) with List-II (process) employed in the manufacture of the substances and select the correct option. [table] List-I | List-II ; a. Sulphuric acid | (i) Haber's Process ; b. Steel | (ii) Bessemer's Process ; c. Sodium hydroxide | (iii) Leblanc Process ; d. Ammonia | (iv) Contact Process [/table]
A) a(i), b(iv), c(ii), d(iii)
B) a(i), b(ii), c(iii), d(iv)
C) a(iv), b(iii), c(ii), d(i)
D) a(iv), b(ii), c(iii), d(i)
Explanation
[Solution from source] Sulphuric acid is made by the Contact process, steel by the Bessemer process, ammonia by Haber's process, and the Leblanc process (soda) is the one left for sodium hydroxide. This gives a(iv), b(ii), c(iii), d(i). Matching sulphuric acid with Haber's process confuses it with ammonia. Answer (4).
