Formulas and Nomenclature of Ionic and Covalent CompoundsFinally, if there are three or more substituent groups, the ring is numbered in such a way as to assign the substituents the lowest possible numbers, as illustrated by the last row of examples.In general, an IUPAC name will have three essential features.Double bonds precede triple bonds in the IUPAC name, but the chain is numbered from the end nearest a multiple bond, regardless of its nature.
Chemical Nomenclature - Widener UniversityA majority of these compounds, however, are referred to by singular names that are unique.NO 2 - Nitrite NO 3 - Nitrate SO 3 2- Sulfite SO 4 2- Sulfate Example: KNO 2 is potassium nitrite, while KNO 3 is potassium nitrate.An excellent presentation of organic nomenclature is provided on a Nomenclature Page. created by Dave Woodcock.
These articles can enhance your knowledge of advanced chemistry topics.There is no simple alternative to memorization in mastering these names.Put on your lab goggles and start learning chemistry with these resources.To avoid all this and to receive fast and efficient help with chemistry homework, select online help wisely.Be careful not to confuse a phenyl (pronounced fenyl ) group with the compound phenol (pronounced feenol ).The terminology of chemical compounds is defined as Nomenclature.

Nomenclature | VIPErIf several substituents are present on the ring, they are listed in alphabetical order.The nomenclature of substituted benzene ring compounds is less systematic than that of the alkanes, alkenes and alkynes.The formulas and structures of these alkanes increase uniformly.
H - Hydride F - Fluoride O 2- Oxide S 2- Sulfide N 3- Nitride P 3- Phosphide Example: Cu 3 P is copper phosphide or copper(I) phosphide.Nomenclature of Simple Binary Compounds This is a basic exercise in naming simple binary compounds.Naming Ionic Compounds Using hypo- and per- In the case where there is a series of four oxyanions, the hypo- and per- prefixes are used in conjunction with the -ite and -ate suffixes.
Fortunately, common numerical prefixes are used in naming chains of five or more carbon atoms.View Homework Help - Homework Nomenclature Key.pdf from CHEMISTRY 142 at Modesto Junior College.
Zumdahl Chemistry Textbooks - Homework Help and AnswersChemistry Help Center is a small team of dedicated chemistry educators and chemistry education researchers.Alkenes and alkynes are hydrocarbons which respectively have carbon-carbon double bond and carbon-carbon triple bond functional groups.If you need help naming ionic compounds, you should check the helpdesk section of my webpage.In order to name complex compounds certain rules have been framed by IUPAC.
Homework resources in Naming Covalent Compounds - Chemistry - Science.The Chemical Formula Calculator is a chemistry formula calculator that shows the chemical formula or chemical name for any element or compound entered in the given space.It is also sometimes called the sodium salt of hypochlorous acid.Hydrocarbons having no double or triple bond functional groups are classified as alkanes or cycloalkanes, depending on whether the carbon atoms of the molecule are arranged only in chains or also in rings.The ChemTeam provides study resources in all standard topics for students in high school and Advanced.Likewise, given a IUPAC name, one should be able to write a structural formula.Basically nomenclature represents the language of chemistry and help in understanding the different.Cation-Anion-Ionic Compound-Formula unit - Covalent Compound. Molecule.
ChemTeam: Main MenuFor examples of how these rules are used in naming alkenes, alkynes and cyclic analogs.Chemical nomenclature is the term given to the naming of compounds.
In the following examples, the first row of compounds show this usage in red.A suffix or other element(s) designating functional groups that may be present in the compound.When an element forms two oxyanions, the one with less oxygen is given a name ending in -ite and the one with more oxygen are given a name that ends in -ate.The structural relationship of rings in a polycyclic compound can vary.Simply put, aliphatic compounds are compounds that do not incorporate any aromatic rings in their molecular structure.
Such common names often have their origin in the history of the science and the natural sources of specific compounds, but the relationship of these names to each other is arbitrary, and no rational or systematic principles underly their assignments.
