Welcome, R G Google M Inbox - rammal... Question Completion Status: QUESTION 4 The d orbitals for a free metal ion (non-complexed) are lower in energy than the orbitals in an octahedral field. True False QUESTION 5 Match each ion with the correct number of UNPAIRED ELECTRONS as predicted in an octahedral field. 003 low spin pa3+ low spin Cu2+ Mn2+ low spin Pa3- high spin 03- high spin Mn2 high spin - high spin

Answer 1

Question 4) Answer is True, because electrons of metal ion and ligand repel each other in octahedral field and hence acquire a higher energy than electrons in free metal ion.

Question 5) Number of unpaired electrons

Co 3+ (low spin) = 0 eletrons

Zn 2+ = 0 eletrons

Pd 3+ (low spin) = 1 electron

Cu 2+ = 1 electron

Mn2+ (low spin) = 1 electron

Ti 2+ = 2 electrons

Pd 3+ (high spin)= 3 electrons

V 2+ = 3 electrons

Ni 2+ = 2 electrons

Co 3+ (high spin)= 4 electrons

Mn 2+ (high spin)= 5 electrons

Cr 2+ (high spin) = 4 electrons
