Complex Ion Charges and Ligand Naming

This video tutorial covers the complex process of naming ligand complexes, focusing on the rules for naming cations and anions, the order of ligands and metals, and the use of prefixes. It provides examples of converting chemical formulas into names and vice versa, emphasizing the importance of understanding charges and the alphabetical order of ligands. The tutorial aims to equip students with the skills to accurately name and interpret ligand complexes.

What is the first step in naming a ligand complex?

• Determine the oxidation state of the metal

• Count the number of ligands

• List the ligands in alphabetical order

• Identify the anion and cation

How should anionic ligands be named?

• By using Roman numerals

• By adding 'ate' to the end

• By adding 'o' to the end

• By using the original molecule's name

What prefix is used for a ligand that appears three times in a complex?

• Tri

• Tetra

• Di

• Penta

In the example 'Tetraamine Dichlorido Rhodium(III) Chloride', what does 'Tetraamine' indicate?

• One rhodium metal

• Two chloride ligands

• Three ammonia ligands

• Four ammonia ligands

What is the charge on the metal in the complex if the overall charge is +1 and the ligands contribute -2?

• +2

• +1

• 0

• +3

When converting a name to a formula, what is the first step?

• Count the number of each type of ligand

• Identify the metal and its charge

• List the ligands in alphabetical order

• Determine the overall charge

In the complex 'Potassium Hexachloridotitanate(IV)', what does 'Hexachlorido' signify?

• Four chloride ligands

• Six chloride ligands

• One chloride ligand

• Two chloride ligands

What is the charge on the titanium in 'Potassium Hexachloridotitanate(IV)'?

• +1

• +3

• +4

• +2

In the example 'Zinc(II) Tetraiodomercurate(II)', what does 'Tetraiodo' indicate?

• One iodine ligand

• Four iodine ligands

• Three iodine ligands

• Two iodine ligands

What is the overall charge of a complex if the metal is +2 and the ligands contribute -4?

• -2

• +4

• +2

• 0
