Coordination compounds: Nomenclature

The video tutorial explains the IUPAC nomenclature rules for naming coordination complexes. It covers the order of naming ions, naming the coordination sphere, and ending the name with appropriate suffixes. The tutorial provides examples to practice naming compounds and demonstrates how to derive chemical formulas from given IUPAC names.

What is the primary purpose of a compound's name according to the IUPAC guidelines?

• To make it easier to spell

• To confuse students

• To identify its physical and chemical properties

• To make it sound scientific

In IUPAC nomenclature, what is the first step in naming a coordination complex?

• Count the number of atoms

• Find the molecular weight

• Identify if the complex is neutral or ionic

• Determine the color of the complex

When naming a coordination complex, which component is named first?

• The metal

• The ligand

• The cation

• The anion

How are multiple identical ligands indicated in the name of a coordination complex?

• By using Roman numerals

• By repeating the ligand name

• By using prefixes like di-, tri-, tetra-

• By using numbers

What suffix is added to the name of an anionic complex?

• -ium

• -ide

• -ate

• -ite

In a neutral coordination complex, how is the name written?

• With commas

• With hyphens

• As separate words

• As a single continuous word

What is the IUPAC name for the complex K4[Mn(CN)6]?

• Potassium hexacyanochromate(IV)
