Question

Which of the coordination compounds (i) to (v) are used for the following processes :
A: Electroplating
B: Removal of excess copper from human body
C: Estimation of hardness of water
(i) DMG (ii) \( Na_2EDTA \) (iii) Cis-platin (iv) D-penicillamine (v) \( K[Au(CN)_2] \)

• A. \( A = iv,\; B = i,\; C = iii \)
• B. \( A = i,\; B = iii,\; C = iv \)
• C. \( A = v,\; B = iv,\; C = ii \)
• D. \( A = iii,\; B = ii,\; C = i \)

Hint:

Remember common applications of coordination compounds: \( K[Au(CN)_2] \) for gold electroplating, EDTA for hardness of water, D-penicillamine for copper removal, and cis-platin as anticancer drug.
