Match List - I with List - II

List - I:
(a) Chlorophyll
(b) Vitamin -

B_{12}

(c) Anticancer drug
(d) Grubbs catalyst

List - II:
(i) Ruthenium
(ii) Platinum
(iii) Cobalt
(iv) Magnesium

Choose the most appropriate answer from the options given below:

Answer: A → IV, B → III, C → II, D → I

Solution

Chlorophyll is a porphyrin holding magnesium at its centre. Vitamin

B_{12}

is a corrin ring built around cobalt. The anticancer agent cisplatin,

cis

[Pt (N H_{3})_{2} C l_{2}]

, is a platinum complex. Grubbs catalyst is a ruthenium carbene used for olefin metathesis. The pairing is chlorophyll with magnesium, vitamin

B_{12}

with cobalt, anticancer drug with platinum and Grubbs catalyst with ruthenium.
