Question

Match the list I with list II and select the correct answer using the code given below.

List I	List II
P. Tribasic acid	1. Hydrazoic acid
Q. Dibasic acid	2. Ortho phosphorous acid
R. Acid hydride of nitrogen	3. Ammonia
S. Basic hydride of nitrogen	4. Orthophosphoric acid

• A. P - (1), Q - (2), R -(3), S - (4)
• B. P - (3), Q - (4), R -(1), S - (2)
• C. P - (4), Q - (2), R -(1), S - (3)
• D. P - (2), Q - (3), R -(1), S - (4)

Answer 1

Answer: (C)

Orthophosphoric acid $⟶H_{3}P{O}_{4\text{ (Tribasicacid) }}$
Orthophosphoric acid $⟶H_{3}P{O}_{3\text{ (Dibasic acid) }}$
Ammonia $⟶N{H}_{3(\text{ Basic hydride of }N)}$
Hydrazoic acid $⟶N_3{H}_{\text{(Acid hydride of }N\text{ ) }}$
