प्रश्न

Answer in brief.

What are the high-spin and low-spin complexes?

टिप्पणी लिखिए

उत्तर

i. High-spin complexes: When crystal field splitting energy is smaller than electron pairing energy, the complexes formed are high-spin complexes.

ii. Low-spin complexes: When crystal field splitting energy is greater than electron pairing energy, the complexes formed are low-spin complexes.
