Which of the following system in an octahedral complex has maximum unpaired electrons?
Options
- Ad^9 (high spin)
- Bd^6 (low spin)
- Cd^4 (low spin)
- Dd^7 (high spin)
Correct answer
D. d^7 (high spin)
Step-by-step solution
( array |c|c| & array c Unpaired electrons array array c d^4 (low spin) -16 array & 2 array c d^7 (high spin) -1 array & 3 array c d^9 (high spin) -1 array & 1 array ) d^7 (high spin) system has maximum unpaired electrons.
