Question

LIST-I contains compounds and LIST-II contains reaction
 

LIST-I		LIST-II
I	\(\text{H}_2\text{O}_2\)	P	\(\text{Mg(HCO}_3\text{)}_2 + \text{Ca(OH)}_2 \rightarrow \)
II	\(\mathrm{Mg(OH)_2}\)	Q	\(\text{BaO}_2 + \text{H}_2\text{SO}_4 \rightarrow \)
III	\(\text{BaCl}_2\)	R	\(\text{Ca(OH)}_2 + \text{MgCl}_2 \)
IV	\(\text{CaCO}_3\)	S	\(\text{BaO}_2 + 2\text{HCl} \rightarrow\)
		T	\(\text{Ca(HCO}_3\text{)}_2 + 2\text{Ca(OH)}_2 \rightarrow \)

Match each compound in LIST – I with its formation reaction(s) in LIST-II, and choose the correct option

• A. I → Q; II → P; III → S; IV → R
• B. I → T; II → P; III → Q; IV → R
• C. I → T; II → R; III → Q; IV → P
• D. I → Q; II → R; III → S; IV → P

Answer 1

The Correct Option is D

(P) \(\text{Mg(HCO}_3\text{)}_2 + 2\text{Ca(OH)}_2 \rightarrow \text{Mg(OH)}_2 + 2\text{CaCO}_3 + 2\text{H}_2\text{O}\) 
(Q) \(\text{BaO}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{H}_2\text{O}_2 + \text{BaSO}_4\)
(R) \(\text{Ca(OH)}_2 + \text{MgCl}_2 \rightarrow \text{Mg(OH)}_2 + \text{CaCl}_2\)
(S) \(\text{BaO}_2 + 2\text{HCl} \rightarrow \text{BaCl}_2 + \text{H}_2\text{O}_2\)
(T) \(\text{Ca(HCO}_3\text{)}_2 + \text{Ca(OH)}_2 \rightarrow 2\text{CaCO}_3 + 2\text{H}_2\text{O}\)
I → Q

II → R

III → S

IV → P

Option (D) is correct.
