Question

Match the following:

Column -I	Column-II
(A) Pure nitrogen	(I) Chlorine
(B) Haber's process	(II) Sulphuric acid
(C) Contact process	(III) Ammonia
(D) Deacon's process	(IV) Sodium azide or Barium azide

• A. A – (III), B – (IV), C – (II), D – (I)
• B. A – (IV), B – (I), C – (II), D – (III)
• C. A – (IV), B – (III), C – (II), D – (I)
• D. A – (I), B – (IV), C – (I), D – (II)

Answer 1

The correct option is C A – (IV), B – (III), C – (II), D – (I)

Pure nitrogen can be obtained from sodium azide or barium azide.
We know that, Haber's process is an industrial method to manufacture ammonia using nitrogen and hydrogen gases.
Contact process is used to prepare sulphuric acid and decon process is used to prepare chlorine.
So the correct answer is
$A–\left(IV\right),B–\left(III\right),C–\left(II\right),D–\left(I\right)$
