JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
Two complexes \([Cr(H_2O)_6]Cl_3\, (A)\) and \([Cr(NH_3)_6]Cl_3\, (B)\) are violet and yellow coloured respectively. The incorrect statement regarding them is
- A \({\Delta _0}\) values of \((A)\) and \((B)\) are calculated from the energies of violet and yellow light, respectively
- B both are paramagnetic with three unpaired electrons
- C both absorbs energies corresponding to their complementary colours
- D \({\Delta _0}\) value for \((A)\) is less than that of \((B)\)
Answer & Solution
Correct Answer
(A) \({\Delta _0}\) values of \((A)\) and \((B)\) are calculated from the energies of violet and yellow light, respectively
Step-by-step Solution
Detailed explanation
\({\Delta _0}\) is calculated from the energies of absorbed radiation not from emitted radiation (complementary colour).
