JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
Given below are two statements :
Statement (I) : In octahedral complexes, when \(\Delta_{\mathrm{o}} \lt \mathrm{P}\) high spin complexes are formed. When \(\Delta_{\mathrm{o}} \gt \mathrm{P}\) low spin complexes are formed.
Statement (II) : In tetrahedral complexes because of \(\Delta_{\mathrm{t}} \lt \mathrm{P}\), low spin complexes are rarely formed.
In the light of the above statements, choose the most appropriate answer from the options given below :
- A Statement I is correct but Statement II is incorrect.
- B Both Statement I and Statement II are incorrect
- C Statement I is incorrect but Statement II is correct
- D Both Statement I and Statement II are correct
Answer & Solution
Correct Answer
(D) Both Statement I and Statement II are correct
Step-by-step Solution
Detailed explanation
In octahedral complex \((\mathrm{CN}=6)\) If \(\Delta_0 \lt \) P.E., then high spin complexes are formed If \(\Delta_0 \gt \) P.E., then low spin complexes are formed But in tetrahedral complex \((\mathrm{CN}=4)\) \(\Delta_t \lt \) P.E., then mainly high spin complexes are…
