Since all acids contain hydrogen, the name of an acid is based on the anion that goes with it. These anions can either be monatomic or polyatomic. The name of all monatomic ions ends in -ide. The majority of polyatomic ions end in either -ate or -ite, though there are a few exceptions such as the cyanide ion \(\left( \ce{CN^-} \right)\).

from nothing but chemistry.

The ending -ide is applied to a MONOATOMIC anion (negative ion) in an ionic compound eg lithium chloride, iron sulfide, magnesium oxide where we have the anions Cl-, S2-, O2- respectively. It is also applied to the more electronegative atom in a covalent compound eg boron nitride BN, carbon diselenide CSe2

Key concepts The -ide ending indicates a binary compound without a polyatomic ion. 5. Rule 4: Drop the a in prefixes ending in a prior to a vowel.

Simple acids, known as binary acids, have only one anion and one hydrogen. These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid.

Consider that hydrogen peroxide again, and compare it to water. when you take a general chemistry class you often have to memorize some of the common polyatomic ions so let's go through a list of some of the ones that you might see in your class so to start off with cation here so a positively charged ion nh4 plus is called the ammonium ion and for anions there are many anions that you should know ch3coo minus is the acetate anion see n minus is the 2011-05-19 · The second part of the naming system that both covalent and ionic compounds have in common is that any binary compound (compound made up of two elements) has the ending -IDE in the name. This -IDE usually replaces the -INE suffix in most elemental names. If you take the element fluor ine, it becomes fluor ide when it is part Chemistry Lecture #38: Naming Covalent Compounds Binary Ionic compounds (which are made of metals and nonmetals) are named by listing the metal first, followed by the nonmetal.

eg. sulfide S 2-, nitride N 3- and phosphide P 3- 1.25 Explain the use of the endings –ide and –ate in the names of compounds A halide ion is a halogen atom bearing a negative charge. The halide anions are fluoride (F−), chloride (Cl−), bromide (Br−), iodide (I−) and astatide (At−).

2020-02-05 · Add the name of the non-metal with an –ide ending. The second component of an ionic compound is the non-metal anion.

If a compound ends in ‘ide’, it contains only two elements.E.g.

The name of least electronegative element is given first, with no ending. The base name of the most electronegative element is given last with an -ide ending , e.g., oxide, nitride, chloride. There are no other endings for covalent compounds. The number of the atoms of each type is specified by the prefixes: 2008-09-27 Learn chemistry function groups name endings with free interactive flashcards.

Our leadership in research includes the traditional areas of physical, analytical, inorganic, and organic chemistry Use of these ending is further illustrated in Sections R-4 and R-5 (see also the 1979 edition of the IUPAC Nomenclature of Organic Chemistry, Rule A-3). Next: R-3.1.2 Hydro prefixes R-3.1.3 Dehydro prefixes R-3.1.4 Substituent prefix names for unsaturated/saturated parent hydrides -ide · Ending (suffix) on monatomic anions that stand alone as ions. Examples: Cl – = chloride ion; N3- = nitride ion · Ending (suffix) appears on only two polyatomic 8 Nov 2015 The suffix -ide is only used if the nonmetal anion is monoatomic (meaning one atom). e.g. chloride ( Cl1- ); bromide ( Br1- ); iodide ( I1- ); The ending - IDE replaces the previous ending of the element name and is not simply added to it; it would therefore be incorrect to write "sodium chlorineide". Why is the anion suffix -ide used to name molecular compounds? From a database of frequently asked questions from the Simple compounds section of General The naming of chemical compounds is often known as nomenclature (accent on the The ide ending means that element holds the negative oxidation number Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, except there is no need to change to an –ide ending, There must be a POLYATOMIC ION in the compound!
