Complex-Metal Matching Solution
This question requires matching specific chemical and biological complexes listed in LIST-I with their central metal atoms provided in LIST-II.
Detailed Matching Breakdown
- Haemoglobin (A): This protein complex is known to contain Iron ($\text{Fe}$) as its central metal ion. Therefore, A corresponds to II (Fe).
- Chlorophyll (B): This photosynthetic pigment features Magnesium ($\text{Mg}$) as the central metal ion. Thus, B matches with IV (Mg).
- Vitamin B$_{12}$ (C): This essential vitamin, also known as cobalamin, contains Cobalt ($\text{Co}$) as its central metal atom. Therefore, C matches with I (Co).
- Cis platin (D): This anticancer drug is a coordination compound of Platinum ($\text{Pt}$). Hence, D corresponds to III (Pt).
Final Answer Derivation
Combining these matches, the correct pairing is:
- A - II
- B - IV
- C - I
- D - III
This sequence is represented as A-II, B-IV, C-I, D-III.
