The mismatched combinations are
A. Chlorophyll - Co
B. Water hardness - EDTA
C. Photography - [Ag(CN)2]-
D. Wilkinson catalyst - [(Ph3P)3 RhCl]
E. Chelating ligand-D- Penicillamine
A. Chlorophyll - Co
B. Water hardness - EDTA
C. Photography - [Ag(CN)2]-
D. Wilkinson catalyst - [(Ph3P)3 RhCl]
E. Chelating ligand-D- Penicillamine
- A, C and E only
- A and C only
- A and E only
- D and E only
The Correct Option is B
Solution and Explanation
- Chlorophyll contains magnesium (Mg), not cobalt (Co), so the combination A is mismatched.
- Water hardness is treated using EDTA, which is correct.
- Photography involves silver salts like \( \text{AgCl} \), not \( [\text{Ag(CN)}_2] \), so the combination C is mismatched.
- Wilkinson catalyst is indeed \( [(Ph_3P)_3 \text{RhCl}] \), which is correct.
- D-Penicillamine is a chelating ligand, which is correct.
Thus, the mismatched combinations are A and C.
