Question

Match List-I with List-II

List-I	List-II
(a) Ca(OCl)2	(i) Antacid
(b) CaSO4· 1/2H2O	(ii) Cement
(c) CaO	(iii) Bleach
(d) CaCO3	(iv) Plaster of Paris

Choose the most appropriate answer from the option given below:

• A. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
• B. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)
• C. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
• D. (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)

Answer 1

The correct option is A

(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

The explanation for the correct answer:

(A)(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

(a) $\mathrm{Ca}{\left(\mathrm{OCl}\right)}_2\to \left(\mathrm{iii}\right)\mathrm{Bleaching}\mathrm{powder}$

(b)${\mathrm{CaSO}}_4.1/2{\mathrm{H}}_2\mathrm{O}\to \left(\mathrm{iv}\right)\mathrm{Plaster}\mathrm{of}\mathrm{Paris}$

(c) $\mathrm{CaO}\to \left(\mathrm{ii}\right)\mathrm{Cement}$

(d)${\mathrm{CaCO}}_3\to \left(\mathrm{i}\right)\mathrm{Antacid}$

Hence, option (A) is correct.

List (i)	List (ii)
(a) Ca(OCl)2	(iii)Bleach
(b)CaSO4.1/2H2O	(iv)Plaster of Paris
(c )CaO	(ii)Cement
(d)CaCO3	(i)Antacid
