The hybridization and magnetic nature of Mn CN 6 4 - and Fe CN 6 3 - , respectively are :

Options

  1. Asp 3 d 2 and diamagnetic
  2. Bd 2 sp 3 and paramagnetic
  3. Csp 3 d 2 and paramagnetic
  4. Dd 2 sp 3 and diamagnetic

Correct answer

B. d 2 sp 3 and paramagnetic

Step-by-step solution

Magnetic property: Due to presence of one unpaired electrons in 3d shell, [ Fe ( CN ) 6 ] 3 − ion is paramagnetic in nature. ​​​​ ∴ hybridisation is d 2 sp 3 and due to presence of unpaired e - complex is paramagnetic in nature ∴ hybridisation is d 2 sp 3 and due to presence of unpaired e - complex paramagnetic in nature
