Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

notable exceptions:
•
water
H2O →aquo
•
ammonia
NH3 →ammine
•
carbon monoxide
CO →carbonyl
• The numbers of ligands in a complex are specified using the
Greek prefixes:
•
di for 2
•
tri for 3
•
tetra for 4
•
penta for 5
•
hexa for 6
• The name of a cationic complex ion ends in the name of the
central metal ion with the oxidation state shown as a Roman
numeral in parantheses at the end of the metal's name, eg,
iron(III).
• The name of an anionic complex ion ends in 'ate',
• chromium(II)→chromate(II)
nickel(II) →nickelate(II)
•
platinum(II) →platinate(II)
• Sometimes the latin name is used, eg,
silver(I)→argentate(I)
iron(II)→ferrate(II)
copper(I)→cuprate(I)
lead(II)→plumbate(II)
gold(I)→aurate(I)
tin(IV) →stannate(IV)
• Ligands are named before the central atom.
• Example: Name the complex ion with the forumla [Fe(CN)6 ]3-
• Anionic ligands have names ending in 'o'.
CN- (cyanide ion) named as cyano.
• The numbers of ligands in a complex are specified using a Greek 
prefix:
6 ligands = hexa → hexacyano
• Oxidation state of the central metal atom is shown with a Roman 
numeral in parantheses at the end of the metal's name:
Central metal ion is iron
Charge on iron: 
•
3- = x + (6 × 1-)
3- = x -6
x = 3+
• Central metal ion: iron(III)
• The complex ion is an anion, therefore the name will end
in ferrate(III).
• Ligands
are
named
before
central
metal
ion:
hexacyanoferrate(III).
• Formula   Ag(NH3)2
+
• Ligand Name
ammine
• No. of Ligands and prefix  2 →di
• Central Ion Name
• silver(I) +1= x + 2(0)
x = +1
• Complex Ion Name
• Diammine silver(I) ion
• (complex is a cation)
Writing the Formula of a Complex
• Identify the central metal ion
• Identify the charge on the central metal ion (shown in
parantheses)
• Identify the ligands
• Identify the number of ligands
• Calculate the total charge on the ligands
• Calculate
the
charge
on
the
complex
ion
= charge on metal ion + total charge on ligands
• Write the formula giving the central metal ion first followed by
the ligands,
• for example, Mn(H2O)6
2+
• If more than one type of ligand is present, anion ligands are
given before neutral ligands,
• for example, CrCl2(NH3)4
+
• Example: 
• write the formula for the complex ion tetra amminecopper(II)
• Identify the central metal ion :
Copper, Cu
• Identify the charge on the central metal ion (shown in parantheses):
2+
• Identify the ligands:
ammine = NH3 (neutral species, charge on ligand = 0)
• Identify the number of ligands:
tetra = 4
• Calculate the total charge on the ligands:
= 4 × 0 = 0
• Calculate the charge on the complex ion
• = charge on metal ion + total charge on ligands = 2+ + 0 = 2+
• Write the formula giving the central metal ion first followed by the ligands :
Cu(NH3)4
2+
Factors affecting the stability of the complex:
• (1) Ability of central metal ion to form complex.
• (2) Ability of ligand to form complex.
(I) Ability of central metal ion to form complex 
1. Acidity  
Acidity means electron accepting power .As the intensity of 
+ve charge i
