Question

Match List-I with List-II:

List-I	List-II
(a) Chlorophyll	(i) Ruthenium
(b) Vitamin – B12	(ii) Platinum
(c) Anticancer drug	(iii) Cobalt
(d) Grubbs catalyst	(iv) Magnesium

Choose the most appropriate answer from the option given below:

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

Answer 1

The correct option is C

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

Explanation for Correct answer:

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

(a) Chlorophyll-(iv)Mg, Chlorophyll is a complex of Mg.

(b)Vitamin B₁₂ -(iii)Cobalt, Vitamin B₁₂ is a complex of CO.

(c) Anticancer drug – (ii)Platin [$\mathrm{Pt}{\left({\mathrm{NH}}_3\right)}_2{\mathrm{Cl}}_2$] used in the treatment of cancer

(d)Grubbs-(i) Ruthenium, catalyst is a series of catalysts containing ruthenium

Hence, option (C) is correct.

List(i)	List (ii)
(a)Chlorophyll	(iv)Mg
(b )Vitamin B12	(iii)Cobalt
(c) Anticancer drug	(ii)Platinum
(d)Grubbs	(i)Ruthenium
