Iupac Nomenclature Of Organic Compounds Rules Of Civility
Rules for naming organic compounds were developed. For the nomenclature of all organic. If you apply the IUPAC nomenclature rules to the five. IUPAC nomenclature of organic chemistry 1 IUPAC nomenclature of organic chemistry The IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as.
Navigation Bar Formulas and Nomenclature of Ionic and Covalent Compounds Adapted from McMurry/Fay, section 2.10, p. 56-63 and the 1411 Lab Manual, p. () Contents: 1. Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons. • A cation is a positively charged ion • An anion is a negatively charged ion. Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion).
Covalent compounds are formed when two nonmetals react with each other. Since hydrogen is a nonmetal, binary compounds containing hydrogen are also usually covalent compounds. • Metal + Nonmetal —> ionic compound (usually) • Metal + Polyatomic ion —> ionic compound (usually) • Nonmetal + Nonmetal —> covalent compound (usually) • Hydrogen + Nonmetal —> Contoh program kerja osis. covalent compound (usually): (Groups IA, IIA, and IIIA) Group IA, IIA, and IIIA metals tend to form cations by losing all of their outermost (valence) electrons. The charge on the cation is the same as the group number.
The cation is given the same name as the neutral metal atom. Ions of Some Main-Group Metals (Groups IA - IIIA). Group Element Cation Ion name IA H H + hydrogen ion Li Li + lithium ion Na Na + sodium ion K K + potassium ion Cs Cs + cesium ion IIA Mg Mg 2+ magnesium ion Ca Ca 2+ calcium ion Sr Sr 2+ strontium ion Ba Ba 2+ barium ion IIIA Al Al 3+ aluminum ion (B-group) and Post-Transition (Group IVA and VA) Metals These elements usually form ionic compounds; many of them can form more than one cation. (The charges of the common transition metals must be memorized; Group IV and V metal cations tend to be either the group number, or the group number minus two.) • Many of these ions have common or trivial names formed from the stem of the element name (the Latin name in some cases) plus the ending -ic or -ous. (-ic endings go with the higher possible charge, -ous endings go with the lower possible charge).
• The systematic names (also known as the Stock system) for these ions are derived by naming the metal first, followed in parentheses by the charge written in Roman numerals. For the metals below that typically form only one charge, it is not usually necessary to specify the charge in the compound name. • For example, iron can form two possible ions, 2+ and 3+. The Fe 2+ ion is known as the ferrous ion (common) or the iron(II) ion (systematic); the Fe 3+ ion is known as the ferric ion (common) or the iron(III) ion (systematic). The mercury(I) cation is a special case; it consists of two Hg + ions joined together, and so is always found as Hg 2 2+. (Hence, mercury(I) chloride is Hg 2Cl 2, not HgCl, while mercury (II) chloride is HgCl 2.) Ions of Some Transition Metals and Post-Transition Metals (Groups IVA and VA). Group Element Anion Ion name IVA C C 4- carbide ion Si Si 4- silicide ion VA N N 3- nitride ion P P 3- phosphide ion As As 3- arsenide ion VIA O O 2- oxide ion S S 2- sulfide ion VIA Se Se 2- selenide ion Te Te 2- telluride ion VIIA F F - fluoride ion Cl Cl - chloride ion Br Br - bromide ion I I - iodide ion IA H H - hydride ion Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group.
