Nomenclature of Inorganic Compounds
The International Union of Pure and Applied Chemistry (IUPAC) has established a set of rules for naming inorganic compounds. These rules are based on the type of compound and the elements present.
Simple ionic compounds are named by stating the name of the positive ion (cation) followed by the name of the negative ion (anion). For example, NaCl is named sodium chloride.
Covalent compounds are named by stating the names of the elements present in the compound, with the suffix “-ide” added to the name of the more electronegative element. For example, H2O is named water.
Acids are named by stating the name of the anion followed by the word “acid”. For example, HCl is named hydrochloric acid.
Use of Prefixes to Indicate the Number of Atoms in a Compound
- mono-
- di-
- tri-
- tetra-
- penta-
- hexa-
Naming Organic Compounds: Naming Compounds Crossword Puzzle Answer Key
The IUPAC rules for naming organic compounds are based on the structure of the compound. The root of the name is based on the number of carbon atoms in the parent chain, and the suffix is based on the functional group present.
Alkanes are named by stating the number of carbon atoms in the parent chain followed by the suffix “-ane”. For example, CH4 is named methane.
Alkenes are named by stating the number of carbon atoms in the parent chain followed by the suffix “-ene”. For example, C2H4 is named ethene.
Alkynes are named by stating the number of carbon atoms in the parent chain followed by the suffix “-yne”. For example, C2H2 is named ethyne.
Aromatic compounds are named by stating the name of the parent aromatic ring followed by the suffix “-benzene”. For example, C6H6 is named benzene.
Use of Functional Groups to Identify Organic Compounds
- Alcohol: -OH
- Aldehyde: -CHO
- Ketone: -CO-
- Carboxylic acid: -COOH
- Amine: -NH2
- Ether: -O-
Naming Coordination Compounds
Coordination compounds are named by stating the name of the metal ion followed by the name of the ligands. The ligands are named by stating the name of the atom or group of atoms that is bonded to the metal ion, followed by the suffix “-ide”.
For example, [Co(NH3)6]Cl3 is named hexamminecobalt(III) chloride.
Use of Ligands and Their Names in Coordination Compounds, Naming compounds crossword puzzle answer key
- Ammonia: NH3
- Chloride: Cl-
- Water: H2O
- Carbon monoxide: CO
- Ethylenediamine: en
Naming Acids and Bases
Acids are named by stating the name of the anion followed by the word “acid”. For example, HCl is named hydrochloric acid.
Bases are named by stating the name of the cation followed by the word “hydroxide”. For example, NaOH is named sodium hydroxide.
Use of Prefixes to Indicate the Strength of Acids and Bases
- Hydro-: weak acid
- Dihydro-: very weak acid
- -ous: weak base
- -ic: strong base
Naming Salts
Salts are named by stating the name of the cation followed by the name of the anion. For example, NaCl is named sodium chloride.
Use of Prefixes to Indicate the Charge of Ions in Salts
- Mono-: +1
- Di-: +2
- Tri-: +3
- Tetra-: +4
- Penta-: +5
- Hexa-: +6
Essential Questionnaire
What is the IUPAC nomenclature system?
The IUPAC nomenclature system is a set of rules established by the International Union of Pure and Applied Chemistry (IUPAC) to provide a standardized and systematic approach to naming chemical compounds.
How do I name inorganic compounds?
Inorganic compounds are typically named using a combination of the element names and their oxidation states. For example, NaCl is named sodium chloride, indicating that it contains sodium in the +1 oxidation state and chlorine in the -1 oxidation state.
What are the rules for naming organic compounds?
Organic compounds are named based on their structure and functional groups. The base part of the name indicates the number of carbon atoms in the parent chain, while the suffix indicates the type of functional group present.
How do I name coordination compounds?
Coordination compounds are named by first naming the ligands, followed by the metal ion. The oxidation state of the metal ion is indicated using Roman numerals in parentheses.
