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 $\longrightarrow H _3 PO _{4 \text { (Tribasicacid) }}$
Orthophosphoric acid $\longrightarrow H _3 PO _{3 \text { (Dibasic acid) }}$
Ammonia $\longrightarrow NH _{3(\text { Basic hydride of } N )}$
Hydrazoic acid $\longrightarrow N _3 H _{\text {(Acid hydride of } N \text { ) }}$
