coordination comp

Question 1

werner theory postulates

Answer 1

• metals show 2 types of linkages/valency (primary and secondary)
• primary valences are ionisable, satisfied by seconday
• secondary are not ionisable, satisfied by anions/neutral species
•special spatial arrangement

Question 2

VBT postulates

Answer 2

•central metal anion makes available empty orbitals
•orbitals hybridise to give eq orbitals
• each ligand has atleast one orbital to overlap
•empty hybird orbitals of central ion overlap w ligand orbitals to form metal ligand coordination cov bond
